The 3 inside angles of a triangle need to equal 180 degrees.
This is a right triangle so the bottom left corner is 90 degrees.
This means the other two angles when added need to equal 180-90 = 90 degrees.
Now you have 8x + 7x = 90
Combine like terms:
15x = 90
Divide both sides by 15
X = 6
Now you have the value for x solve the two angles:
8x = 8(6) = 48
7x = 7(6) = 42
Top left = 48 degrees
Bottom right = 42 degrees
Answer:
24, 36, and 48
Step-by-step explanation:
those numbers are the most high common factor of 24, 36, and 48.
Answer:
14 people
Step-by-step explanation:
- A sample is defined as a set of objects or people selected by a given criteria to be studied.
-The sample's elements are unknown pre-study.
-In this case the group of 30 is the population and the 14 people is the sample.
X-10 + 2x + 1= 90°
you combine like terms:
x+2x= 3x and -10 + 1 = -9
So,
3x - 9 = 90
+9 +9
3x=99
Divide by 3,
x= 33
First Angle: x-10 (plug in 33 for x)
33-10 = 23°
Second Angle: 2x + 1 (plug in 33 for x)
2(33)+1
66+1= 67°
To Check if it’s correct and make a 90° angle:
Add 67° plus 23° which equals 90°
First angle: 23°
Second angle: 67°
Hope that help!!
Okay. The formula for the area of the circle is A = πr². To find the radius, we would first do the steps in reverse. Let's divide the area by pi (3.14) 706.5/3.14 is 225. With that, the square root of 225 is 15, because 15² is 225. There. The radius of the circle is 15 feet.
