Answer:
56
Explanation:
angle BAD is an exterior angle of triangle ABC
angle x and angle C are opposite interior angles of exterior angle BAD
An exterior angle of a triangle is equal to the sum of its opposite interior angles
Hence angle BAD = x + angle C
we are given that angle BAD = 116 and angle C = 60
So 116 = x + 60
Notice that we just created an equation that we can use to solve for x
We now solve for x algebraically
116 = x + 60
Subtract both sides by 60
116 - 60 = 56
60 - 60 cancels out
We're left with x = 56
