Respuesta :
Since a complementary angle is two angles that equal 90 degrees the compliment of angle B would be 30 degrees since 60+30 = 90.
Solutions
Complementary angle are two angles whose sum is 90°. We know that Angle b measures 60°.
60° + (X) = 90°
90° - 60° = (X)
90° - 60° = 30°
(X) = 30°
30° complementary to Angle B
