Answer: Step-by-step explanation:

Supplementary Angles. (Linear Pair)

111 + 3x + 3 = 180

Add 111 and 3 together

114 + 3x = 180

Subtract 114

3x = 66

Divide by 3

x = 22

Answer:

Two angles are called supplementary when their measures add up to 180 degrees. And x=22

Step-by-step explanation:

if you enter 22 in as x and times it by 3 and add 3 to it you get 69 add 111 you get 180 therefore it is supplementary and x=22
