Question

Find the values of a and b​

Answer 1

a = 14°

b = 36°

Explanation:

4b - 12 + 48 = 180 (supplementary)

Rearrange

4b = 180 - 48 + 12

4b = 144

b = 36°

4a - 8 + 4b - 12 = 180 (supplementary)

sub b = 36 into equation

4a - 8 + 144 - 12 = 180

Rearrange

4a = 180 - 144 + 12 + 8

4a = 56

a = 14°
