Question

Find A, given that a = 18.2, B=62°, and C= 48°. Round to the nearest whole degree.

Answer 1

Explanation:

If we are given angles B and C, then all we have to do is add them together and then subtract that from 180 since all the angles of a triangle have to add up to equal 180.

62 + 48 = 110

180 - 110 = 70

Angle A = 70°
