The length of other leg of a right triangle is 6.633 cm
What is a right triangle?A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.
To find the length of hypotenuse the formula is c² =a² + b² , where c is hypotenuse and a, b are sides of triangle
From the question hypotenuse(c)= 12 cm and one of its leg(b) =10cm
12² =a² +10²
144= a² + 100
44= a²
a= 6.633
Thus the length of other leg of a right triangle is 6.633 cm

From a horizontal distance of 80m, the angle of elevation to the top of a flagpole is 180. Calculate the height of the flagpole.
Answer:
0
Step-by-step explanation:
From a horizontal distance of 80m, the angle of elevation to the top of a flagpole is 180. Calculate the height of the flagpole.
We solve the above question using the trigonometric function of Tangent
The formula is given as:
tan θ = Opposite/ Adjacent
θ = 180°
Adjacent = 80m
Opposite = Height = x
Hence,
tan 180 = x/80
Cross Multiply
x = tan 180 × 80
x = 0m
The height of the flag = 0
The Front and Back sides are both triangles. Explain why he isnt going to divide the base x height by 2.

A chord is 10cm from the centre of a circle of radius 15cm. Find the length of the chord.
Answer: 21.44 cm
Step-by-step explanation:
Given
Radius r=15 cm
distance of chord from the center is 10 cm
From the figure, the length of the chord is AC
Applying Pythagoras
[tex]\Rightarrow AO^2=OB^2+AB^2\\\Rightarrow AB^2=15^2-10^2\\\Rightarrow AB^2=225-100=115\\\Rightarrow AB=\sqrt{115}=10.72\ cm[/tex]
The length of the chord is [tex]AC=2AB=21.44\ cm[/tex]

It can be deduced that the addition of -3 and 4 will be 1.
How to add the numbersIt can be deduced that the addition of -3 and 4 will be;
= -3 + 4
= 1
When the winning score in golf is the lowest number, the lowest number is -1.
The value of the expression -273 - (-576) will be:
= -273 - (-576)
= -273 + 576
= 303
Also, -56/4 = -14. The value of the expression (2 - 19) + (-12) will be:
= (2 - 19) + (-12)
= -17 - 12
= -29
The value of -2x = 22 will be:
-2x = 22
Divide both side by -2
-2x/-2 = 22/-2
x = -11
The value of 5 + 3x = -22 will be;
5 + 3x = -22
5x = - 22 - 5
3x = -27
x = -27/3 = -9
5(x + 3) = 35
5x + 15 = 35
5x = 35 - 15
5x = 20.
5x/5 = 20/5
x = 4

a. 30°
b. 45°
c 54
d.55
e. 135
Answer:
The measure of angle 2 is 45 degrees
Step-by-step explanation:
Mathematically, when two angles are supplementary, the sum of these angles will be equal to 180 degrees
Let the measure of angle 2 be x
The measure of angle 1 is 3 times this and that will be 3 * x = 3x
The sum of both will be 180
x + 3x = 180
4x = 180
x = 180/4

A bag contains 3 red marbles, 7 blue marbles and 5 green marbles. If two marbles are
drawn out of the bag, what is the probability, to the nearest 100oth, that both
marbles drawn will be blue?
Answer:
0.218
Step-by-step explanation:
Probability is the likelihood of an event.
According to the word problem, of the 15 marbles, there are 7.
Since there are 7 blue marbles, the expected outcome of both events is 7.
The probability of the first blue marble is 7/15.
The probability of the second blue marble is 7/15.
To find the probability of both marbles being drawn, we must multiply both fractions.
Like this,
7/15 ⋅ 7/15 = 49/225.
49/225 in decimal form is 0.21777778
0.21777778 rounded to the nearest hundredth is 0.218.
Therefore, the probability of two blue marbles being drawn out of the bag is 0.218.

The sum of two numbers is 17
The difference of those same two numbers is 3
Find the two numbers
Graph the equations, and determine your answer by marking the point of intersection
The two numbers are 7 and 10 whose sum is 17 and whose difference is 3.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that the sum of two numbers is 17 and the difference of those same two numbers is 3.
We need to find those two numbers.
Let x and y are the two numbers.
Sum of two numbers is 17
x+y=17..(1)
Difference of two numbers is 3
x-y=3..(2)
From equation 1,
x=17-y
Now substitute this in equation 2.
17-y-y=3
17-2y=3
17-3=2y
14=2y
Divide both sides by 2
y=7
Now add y value in equation 1
x+7=17
Subtract 7 from both sides
x=10
Hence, the two numbers are 7 and 10.
