15° and 165°
Step-by-step explanation:
Step 1 :
Let x and y denote the angles with x as the smaller angle and y as the larger angle
When 2 angles are supplementary, the sum of both the angles is 180 degrees.
Hence x + y = 180
Step 2:
Given that the larger angle is 15 more than 10 times the smaller angle
Hence y = 15 + 10 x
Step 3 :
Solving for the 2 equations we have
11x = 165 => x = 15
=> y = 180-15 = 165
Hence the 2 angles are 15 and 165 degrees.
Answer: Boutta snitch on you. CHHS 10th grade
Step-by-step explanation:
a straight line = 180 degrees so:
4x+16 + 92 = 180
4x +108 = 180
4x=72
x = 72/4 = 18
x= 18
Answer:
Area = 6.25
ft^2
Step-by-step explanation:
Area = ![\pi \\](https://tex.z-dn.net/?f=%5Cpi%20%5C%5C)
![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D%20)
The diameter is 5 feet. That makes the radius 2.5 feet
Area = ![\pi \\](https://tex.z-dn.net/?f=%5Cpi%20%5C%5C)
![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D%20)
Area = ![\pi \\](https://tex.z-dn.net/?f=%5Cpi%20%5C%5C)
![2.5^{2}](https://tex.z-dn.net/?f=2.5%5E%7B2%7D%20)
Area = 6.25
