Question

One angle of the triangle is 37° the other is 42° What is the measure of the exterior angle x (1 point)

Answer 1

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two opposite interior angles.

Let's call the measure of the exterior angle x.

Since one interior angle is 37°, and the other interior angle is 42°, we have:

x = 37° + 42°

x = 79°

Therefore, the measure of the exterior angle x is 79°.
