Question

1. if one exterior angle of a triangle is 80 degrees and another is 110 degrees, what is the third? 180 degrees 170 degrees 190 degrees 200 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 \(80 + 110+x=360\).

Step3: Solve for \(x\)
