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