An angle is 20° more than three times the given angle . if the two angle are supplementary , then 1 the angle are ,70°/4,290°/4 , 40°,140° , 60°,120° ,40°,50°​

Answer 1

Step-by-step explanation:

let,

given angle be x

1st angle - x

2nd angle -20 +3x

x+20+3x = 180 degrees

4x=160degrees

x=40degrees

1st angle = x=40 degrees

2nd angle = 20+3x = 20+3(40) = 20 +120 =140degrees
