Question

The angles of a triangle ABC are such that angle B is double of angle A; and angle C is 20° more than angle A. What is the measure of each angle?
Please explain briefly. The answer will be marked as brainliest

Answer 1

let angle A be x
angle B= 2x
angle C=20°+x
2x +20°+x+x =180°(angle sum property)
4x+20°=180°
4x=180°-20°
4x=160°
x=160/4=40°
angle B=2x=40*2=80°
angle C=20°+x=20°+40°=60°
angle A=x=40°
check
40°+80°+60°=180°
