Question

The angles shown below are supplementary: What is the value of x? 10° 11° 20° 22°

Answer 1

Answer: X=10

Since the two angles and supplementary, we know that they have a sum of 180°. So we can write:

180=10x+80
subtract 80 from both sides
100=10x
divide both sides by 10
10=x

Answer: X=10
