Answer:
x = 25
Step-by-step explanation:
Looking at the triangle we know that it is a right triangleor a 90⁰ triangle.
(2x + 15)⁰ + x⁰ = 90⁰
2x + 15⁰ + x⁰ = 90⁰
2x + x + 15⁰ = 90⁰
3x + 15⁰ = 90⁰
3x + 15⁰ - 15⁰ = 90⁰ - 15⁰
3x = 75⁰
3x / 3 = 75⁰ / 3
x = 25⁰
Now plug the x value in the missing angles.
2x + 15⁰
2(25⁰) + 15⁰
50⁰ + 15⁰
65⁰
According to the sum of triangle, all angles add up to 180⁰. Even though this is a right triangle, it should add up 180⁰ in order to be a triangle.
65⁰ + 25⁰ + 90⁰ = 180⁰

A pedagogical research institute wanted to test a new method for teaching geometry by assessing whether It helps students achieve higher grades. They decided to conduct a study using A volunteering high school with a total of 750 students At the beginning of the semester, 2 out of the 4 high schools were randomly picked to use the new teaching method, while the remaining 2 schools kept teaching with traditional methods. The first pair had a total of 400 students, and the second pair had a total of 350 students. By the end of the semester, the researchers compared the average scores in the geometry section of the final exam for each pair of schools. What type of statistical study did the researchers use
Answers
Answer:
Experimental Statistical Study
Step-by-step explanation:
Of the three types of statistical study, the one used by the researcher in this question is the experimental statistical study and the reason is as follows:
From the question, a study was conducted on a total of 4 high schools; these high schools were further divided into 2 pairs.
Each pair were subjected to or experimented with different method of teachings. At the end of the semester, the average were compared.
This implies that both pairs were experimented based on different teaching methods and the result of the methods were measured in order to determine which of the methods is better.
This type of study is experimental
Answer:
Experiment ; No, because the schools could be very different, meaning the randomization won't smooth out other effects.

Angle measures 82.6° less than the measure of its supplementary angle. What is the measure of each angle
Answers
Answer:
131.3°, 48.7°
Step-by-step explanation:
Let x represent the larger angle. Then x-82.6 is the smaller one. Their sum is ...
x +(x -82.6) = 180
2x = 262.6
x = 131.3
x -82.6 = 48.7
The two angle measures are 48.7° and 131.3°.

What are the zeros of the polynomial function f(x) = x3 - 2x2 - 24x? (1 point)
1) -6, 0, 4
2) 6, 0, -4
3) -6, 0, -4
4) 6,0, 4
Answers
f(x) = x³ - 2x² - 24x
x³ - 2x² - 24x = 0
x(x² - 2x - 24) = 0
x = 0
x² - 2x - 24 = 0
a = 1, b = -2, c = -24
Delta = (-2)² - 4 * 1 * (-24) = 4 + 96 = 100
x = (-(-2) - 10)/(2 * 1) = -8/2 = -4
x = (-(-2) + 10)/(2 * 1) = 12/2 = 6

Step-by-step explanation:
The square by the vertex indicates that this is a right angle. A right angle measures 90°. So what you can do is subtract the 70° from the 90°, to get 20°.

regular price ticket cost?
Write the equation and solve:
Answers
Answer:
The regular cost of each ticket is $30
Step-by-step explanation:
Hi,
You and three friends means there was a total of 4 people. Your equation is...
4x - 20 = 100
Remember to add the -20 since there was a coupon that saved you $20.
Now solve...
4x - 20 = 100
+ 20 on both sides
4x = 120
Divide by 4 on both sides
x = 30
The regular cost of each ticket is $30

Mr. Gow needs to build a wheelchair access ramp for the school's auditorium. The ramp must rise a total of 3 feet to get from the ground to the entrance of the building. In order to follow the state building code, the angle formed by the ramp and the ground cannot exceed 4.75°.
Mr. Gow plans from the planning department that call for the ramp to start 25 feet away from the building code?
a. Draw an appropiate diagram. Add all the measurements you can. What does Mr. Gow need to find?
b. According to the plan in part (a), what angle will the ramp make with the ground? Will the ramp be to code?
c. If Mr. Gow builds the ramp exactly to code, how long will the ramp be? In other words, at least how far from the building must the ramp start in order to∞ meet the building code? Show all work.

Answer:
a. see below for diagram. Angle for the length; length for the angle
b. 6.84°; not to code
c. 36.1 ft
Step-by-step explanation:
a. The diagram is shown below. Mr. Gow needs to find the angle it makes in order to determine if it is up to code. Alternatively, Mr. Gow needs to find the required length for a ramp that meets code.
__
b. The angle the ramp makes can be found using the tangent relation.
Tan = Opposite/Adjacent
tan(angle) = 3/25
angle = arctan(3/25) ≈ 6.84°
The ramp will make a 6.84° angle with the ground. It will not meet code.
__
c. We can find the distance from the building where the ramp must start using the same trig relation.
tan(4.75°) = (3 ft)/(distance)
distance = (3 ft)/tan(4.75°) ≈ 36.1 ft
The ramp must start 36.1 feet from the building to exactly meet code.
