For converting radian to degree we simply place pi as 180 degree.
So the given angle in radians =

Now can place pi = 180 degree in this angle.
So angle in degree =

So given angle in degree = -570 degree
Answer: x=-6
Step-by-step explanation:
x+55+x+51+86=180
2x+106+86=180
2x+192=180
2x=-12
x=-6

Graph :
Choose any two points. (0 , 2) and (-1 , -2)
Rate of change = Change in y ÷ Change in x

Table:
Rate of change = ![\frac{-2-[-6]}{2-0}](https://tex.z-dn.net/?f=%5Cfrac%7B-2-%5B-6%5D%7D%7B2-0%7D)

Answer:
Step-by-step explanation:
The two acute angles add up to 90 degrees. That's because every triangle has 180 degrees and a right angle is 90 degrees.
<m1 + <m2 + 90 = 180 Subtract 90 from both sides.
<m1 + <m2 + 90 - 90 = 180 - 90 Combine
<m1 + <m2 = 90
Let m1 = 9*m2 Substitute.
9m2 + m2 = 90 Combine
10 m2 = 90 Divide by 10
10m2/10 = 90/10
m2 = 9
m1 = 9*m2
m1 = 9 * 9
m1 = 81
The right angle = 90
m1 = 81
m2 = 9
