En resumen

A + B + C = 180 B = 2A C = 3A A + 2A + 3A = 180 6A = 180 A = 180 / 6 A = 30° B = 2(30°) = 60° C = 3(30°) = 90° A = 30° ; B = 60° ; C = 90°.

A + B + C = 180

B = 2A

C = 3A

A + 2A + 3A = 180

6A = 180

A = 180 / 6

A = 30°

B = 2(30°) = 60°

C = 3(30°) = 90°

A = 30° ; B = 60° ; C = 90°.
