Question: What is the measure of an exterior angle of a triangle if the two remote interior angles measure 40 degrees and 60 degrees?

Options:

1. 80 degrees
2. 100 degrees
3. 120 degrees
4. 140 degrees

Correct Answer: 100 degrees

Solution:

The exterior angle is equal to the sum of the two remote interior angles. Therefore, the exterior angle measures 40 + 60 = 100 degrees.
