Answer 1

ans

180-60-50=70

180-30-90=60

180-30-110=40

2x+50=180

x=65

3=180

x =60

90+3x=180

Answer 2

1) 50°+60°+x =180°

110°+x=180°

x=180°-110°

x=70°

2) 30°+90°+x=180°

120°+x=180°

x=180°-120°

x=60°

3) 30°+110°+x=180°

140°+x=180°

x=180°-140°

x=40°

4) 50°+x+x=180°

50°+2x=180°

2x=180°-50°

2x=130°

x=130°÷2

x=65°

5) x+x+x=180°

3x=180°

x=180°÷3

x=60°

6) 2x+x+90°=180°

3x+90°=180°

3x=180°-90°

3x=90°

x=90°÷3

x=30°
