Question

How many degrees is the exterior angle of a triangle (w) if the non-adjacent angles (z and y) are 46 and 85?

Answer 1

m∠w = 131°

Explanation:

Step 1: Find m∠zwy (Using sum of interior angles of a triangle)

m∠zwy = 180 - (46 + 85)

m∠zwy = 49°

Step 2: Find exterior angle (using Definition of Supplementary Angles)

m∠w = 180 - 49

m∠w = 131°
