Question

What is the measure of ∠A, the exterior angle of the triangle shown below?

Answer 1

Explanation:

38+50=angle A(the sum of two interior opposite angle is equal to the external angle formed)

88=angle A

Answer 2

88

Explanation:

Each triangle has a sum of 180 degrees. So we find the missing angle with this rule.

180-38-50.

The angle is 92 degrees.

Now to find the angle of A, each angle adds up to 180 on a line. so 180-92. So you get 88
