Question

7) If angles of measures (x — 2)° and (2x + 5)º are a pair of supplementary angles. Find the
measures.what is the answer​

Answer 1

Step-by-step explanation:

According to the question,

(x-2)°+(2x+5)°=180°

(x-2)°+2x°=180'-5'

(x+2)'+2x'=175'

X'+2x'=175'-2'

3x'=173'

X'=173/3

X=57.6'
