Question

An angle measures 130.4° more than the measure of its supplementary angle. What is the measure of each angle?

Answer 1

155.2

Explanation:

let x be the supplimentary angle

then the angle is

130.4+x

we have

130.4+x+x=180

2x=49.6

multiply both sides with 2

x=24.8

then the angle is

130.4+24.8

155.2

Answer 2

Answer: 24.8 and 155.2

Explanation:

x+x+130.4=180

2x=49.6

x=24.8
