Answer:

x = 39

Explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

108° is the external angle of the complete triangle. thus

unknown + (37 + 32) = 108, that is

unknown + 69 = 108 ( subtract 69 from both sides )

unknown = 39

Now the unknown = x ( vertical angles ), that is

x = 39
