Question

One of the angles of a pair of supplementary angles is 20° more

than its supplement. Find the angles?

Answer 1

Answer:

160°

supplementary degree = 180°

therefore

180 - 20

= 160

Answer 2

Answer:

sum of the supplementary angles is 180°

Step-by-step explanation:

let sapplementry angle measure x°

20 + x = 180

20 + x - 20 = 180 - 20

x = 160

therfore supplementary angles are 20° and 160°
