Question

Find the measure of angle A.

Angle 1. x+59
Angle 2. 84
Angle 3. x+51

I already know x= -7 But the measure of angle A is on the outside of the triangle

Answer 1

Ans: The measure of exterior angle i.e angle A is -52⁰.

You meant to say that the measure of an angle A is on exterior angle so let me elaborate it you clearly,

`x + 59 \\ = - 7 + 59 \\= - 52`
