Question

What is the measure of the exterior angle X if the top of the triangle is 37° and the bottom right is 42°

Answer 1

To find the measure of the exterior angle "X," we need to use the fact that the sum of the measures of the exterior angles of any triangle always equals 360°.

First, we can determine the measure of the third angle by subtracting the given angles from 180°:
Third angle = 180° - (37° + 42°)
Third angle = 180° - 79°
Third angle = 101°

Then, we can calculate the measure of the exterior angle X by subtracting the third angle from 360°:
X = 360° - 101°
X = 259°
