Finding the Measure of an Exterior Angle
Mary is also a civil engineer, and she is building a triangular community garden. She knows two angles in the triangular garden, diagramed below.

A triangle has angle measures 92 degrees, 27 degrees, and a degrees. The exterior angle to a degrees is b degrees.

What are the measures of interior angle a and exterior angle b?

°
b =
°

a = 61°
b = 119°

Explanation: a = 180 − (92 + 27) = 61°. The exterior angle b is supplementary to a (or equals the sum of the two remote interior angles), so b = 180 − 61 = 119° (or 92 + 27 = 119°).
