Question

1. given two exterior angles of a triangle are 120° and 145°, what is the measure of the third exterior angle? 115 degrees 95 degrees 135 degrees 105 degrees

Explanation:

Step1: Recall the sum of exterior angles of a triangle

The sum of the exterior angles of any triangle is \(360^{\circ}\).

Step2: Let the third exterior angle be \(x\)

We know that \(120 + 145+x=360\).

Step3: Solve for \(x\)
