Respuesta:
a = 90°; b = 60°; c = 30°
Explicación paso a paso:
a = b + 30°
b = 2c --> c = b/2
Para todo triángulo la suma de sus ángulos internos es 180.
a + b + c = 180°
(b + 30°) + b + b/2 = 180°
2b + b/2 = 180° - 30°
5b/2 = 150°
b = (150°/5) * 2
b = 60°
a = b + 30° --> a = 90°
c = b/2 --> c = 30°
