Question

Need help figuring this out I think the answer is 30.

Answer 1

Note that the sum of the angles in a triangle is always 180 degrees

angle A + angle B + angle C = 180

From the given problem :

angle A = 60

angle C = 90

using the formula above :

60 + angle B + 90 = 180

angle B = 180 - 150

angle B = 30

Therefore the unknown angle is 30 degrees
