Question

find the measure of two supplemenatry with x° and (2x+20°)

Answer 1

x+2x+20=180
3x=180-20
3x=160
x=160/3
x=53.3
first angle 53.3
second angle126.6

Answer 2

x+ 2x+20= 180 . 3x=180 -20=160 . x= 160/3 = 53.3° therefore smaller angle = x= 53.3° and larger angle=2x+20 =2×53.3+20= 126.6° ans . THANKYOU
