Answer 1

Angle A=50°

Angle B=130°

Angle C=20°

Explanation:

Angles P+Q+A= 180°

So if P=90° and Q=40° that equals 130° so, 180°-130°=50°

Angle A=50°

Angles A+B= 180°

Angle A=50° so, 180°-50°=130°

Angle B=130°

Angles B+C+R= 180°

So if B=130° and R=30° that equals 160° so, 180°-160°=20°

Angle C=20°
