We can use a scientific calculator or look up the sine of 25 degrees in a table of trigonometric values. The answer would be approximately 2.13 cm.
What do you mean by Right Angle Triangle?A right angle triangle is a triangle in which one of the angles is equal to 90 degrees. In other words, it is a triangle in which one angle is a "right angle." Right angle triangles are commonly used in geometry and trigonometry, and they play a crucial role in many real-world applications, such as surveying, construction, and navigation.
In a right triangle, the length of one side can be found using the sine function. The sine of an angle in a right triangle is defined as the ratio of the length of the opposite side to the length of the hypotenuse. In this case, the angle MNO is 25 degrees, so we can write the following equation to find the length of side MN:
MN = NO * sin(25°) = 4 cm * sin(25°)
To find the numerical value of MN, we can use a scientific calculator or look up the sine of 25 degrees in a table of trigonometric values. The answer would be approximately 2.13 cm.

Answer:
x = 38
∠P = 26º
Step-by-step explanation:
The sum of the angle in a triangle is 180
x + (x + 78) + (x - 12) = 180
Combine like terms
3x + 66 = 180
Subtract 66 from both sides
3x = 114
Divide both sides by 3
x = 38
-----------------------
∠P = x - 12
∠P = 38 - 12
∠P = 26º
Answer:
Step-by-step explanation:
(x+78)+(x-12)+x=180
3x+66=180
3x=114
x=38
P=26

what is the slope line perpendicular to the equation 4x+3y=9
Answer:
m=3/4
Step-by-step explanation:
first, let's put the line 4x+3y=9 from standard form (ax+by=c) into slope-intercept form (y=mx+b)
we have the equation 4x+3y=9
subtract 4x from both sides
3y=-4x+9
divide by 3
y=-4/3x+3
perpendicular lines have slopes that are negative and reciprocal. If the slopes are multiplied together, the result is -1
so to find the slope of the line perpendicular to the line y=-4/3x+3, we can take the slope of y=-4/3x+3 (-4/3) multiply it by a variable (this is our unknown value), and have that set to -1
(m is the slope value)
-4/3m=-1
multiply by -3/4
m=3/4
therefore the slope of the perpendicular line is 3/4

how to tell the transformation of graphs?

Step-by-step explanation:
if the parent function, y=f(x) has a number added (y=f(x)+4) the graph will be translated up. If the parent function has a number subtracted, y=f(x)-4, the graph will be translated down. The image explains more simply, and there are more possible translations (shown in image)
Tell whether the statement is always, sometimes, or never true. Explain.
1. If x and y are supplementary angles, then y is acute.
2. If x and y are complementary angles, then x is obtuse.
Answer:
1. If x and y are supplementary angles, then y is sometimes acute because supplementary angles are angles that add up to 180 degrees. So, y can be acute while x can be obtuse, y can be obtuse while x can be acute, or both can be right angles.
2. If x and y are complementary angles, then x is never obtuse. Complementary angles are angles that add up to 90 degrees, and obtuse angles are angles over 90 degrees, so it's impossible to have an obtuse angle as a complementary angle.
Step-by-step explanation:
Answer:
1) Sometimes
2) Never
Step-by-step explanation:
1) you could have two angles add up to 180 degrees and one of them could be less than 90
example, x = 140° and y = 40°
2) if two angles are complementary then their sum is 90° so neither angle must be less than 90°, thereby making them both acute angles

Answer:
Area = 115 yards
Step-by-step explanation:
If we look at this as two rectangles, you can see that the area of one is going to be 10yd multiplied by 9yd, which gives us 90yd. The other smaller rectangle will be 6yd multiplied by 4yd, which gives us 24yd.
Now, add the two areas back together to get the area of the whole shape and you get A=115yd.

Here are two stories: The initial freshman class at a college is 10% smaller than last year’s class. But then during the first week of classes, 20 more students enroll. There are then 830 students in the freshman class.
A store reduces the price of a computer by $20. Then during a 10% off sale, a customer pays $830
here are two equations: 0.9x+20=830, 0.9(x-20)=830
A. Decide which equation represents each story.
B. Explain why one equation has parentheses and the other doesn't.
C.Solve each equation, and explain what was the solution means in the situation.
Thank you to the people that answered my questions!
Using proportions, it is found that:
a. The equations are related to the stories as follows:
0.9x+20=830 = Class in college.0.9(x-20)=830 = Computer price.b. The parenthesis is because of the 10% reduction was applied over the value subtracted by $20.
c. The solutions are given as follows:
x = 900: Size of the freshmen class in the previous year.x = 942: Original price of the computer.What is a proportion?A proportion is a fraction of a total amount, and are used along with basic arithmetic operations such as multiplication or division to find the desired measures in the context of a problem.
One example of application of proportions is for percentage problems, as the decimal equivalent of the percentage, considering discounts or increases, is multiplied by the total amount to find the equivalent amount.
For the college class, we have that:
It is 10% smaller than last year's amount of x, that is, 90% of x = 0.9x.Then 20 is added to this amount, that is, 0.9x + 20.The equivalent amount is of 830 students, hence the equation is:
0.9x + 20 = 830
The solution is found as follows:
0.9x = 810
x = 810/0.9
x = 900.
Which is the size of the freshmen class in the previous year.
For the computer in the store, we have that:
The price of x was reduced by $20, hence x - 20.Over the price reduced by $20, a reduction of 10% was applied, hence the price paid is of: 0.9(x - 20).This price is of 830, hence the equation is:
0.9(x - 20) = 830
The solution, which is the initial price of the computer, is found as follows:
x - 20 = 830/0.9
x = 20 + 922
x = 942.

Miguel and Bartholomew each have credit card debt. Miguel owes $2000 and makes a monthly payments, reducing his debt by $250 per month. Bartholomew owes $1500 and makes monthly payments, reducing his debt by $150 per month. Let m represent The number of months and b represent the balance on the credit card account in dollars. Write a system of 2 equations to represent this situation. When will Miguel and Bartholomew owe the same amount of money?
Answer:
Miguel:
b = 2000 - 250m
Bartholomew:
b = 1500 - 150m
When m = 5
Step-by-step explanation:
Let
m = The number of months
b = balance on the credit card account in dollars.
Miguel owes $2000 and makes a monthly payments, reducing his debt by $250 per month.
Miguel:
b = 2000 - 250m
Bartholomew owes $1500 and makes monthly payments, reducing his debt by $150 per month
Bartholomew:
b = 1500 - 150m
When will Miguel and Bartholomew owe the same amount of money?
Miguel balance = Bartholomew balance
2000 - 250m = 1500 - 150m
2000 - 1500 = -150m + 250m
500 = 100m
m = 500/100
m = 5 months

The probability of the complement of event A P(Ac), which is the event of a place to not be a city, is 4/7. Option C is correct.
How to find the probability of an event?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
A place from this table is chosen at random. Let event A= the place is a city.
The total number of places are 7 given in the table.There are total three places which are city. Thus, the probability of a country to be a city is,
[tex]P(A)=\dfrac{3}{7}[/tex]
Now, for its complement, the probability of a place not be a city is,
[tex]P(A^c)=1-\dfrac{3}{7}\\P(A^c)=\dfrac{7-3}{7}\\P(A^c)=\dfrac{4}{7}[/tex]
Thus, the probability of the complement of event A P(Ac), which is the event of a place to not be a city, is 4/7. Option C is correct.
