Answer 1

Hola:

1. 80°=90°-180°-2x/2

80°=90°-(90-x)

80°=90°-90°+x

80°=x

Rpta: 80°

2.CALCULA: "X°"

40+2B+4n=180

20+B+2n=90

B+2n=70

B+2n+180-W=180

70+180-W=180

250-W=180

W=70

Te piden: X=90°+W/2

X=90°+35°=125°

Rpta: 125°

3.

180-130°=180°-2x/2

50=90°-x

x=40°

Rpta: 40°

4.

x=48°-36°/2

x=12°/2

x=6°

Rpta: 6°
