Answer 1

Respuesta:

2.a.

x+20°+x+2x = 180°

4x = 180° - 20°

x = 160°/4

x = 40°

A = x + 20 = 60°

B = 2x = 2(40) =80°

C = x = 40°

2.b.

(3x+-10°) + 2x + (110°-x) = 180°

(3x+2x-x) - 10°+110° = 180°

4x = 180°- 100°

x = 80°/4

x = 20

O = 2x = 2(20) = 40°

P = 110°-x = 110°-20° = 90°

Q = 3x-10° = 3(20)-10° = 60°-10° = 50°

Explicación paso a paso:

eso es todo lo que pude hacer, espero te ayude
