Question

Q1. If you draw a triangle with angles that measure 25 degrees and 60 degrees, what will be the measure of the third angle?

Q2. If angle 1 and angle 2 are supplementary, and angle 1 measures 80 degrees, what is the measure of angle 2?

Answer 1

Q1. 95 degrees

Q2. 100 degrees

Explanation:

When you create a triangle, all angle measures must equal 180 degrees.

So, using that information, take 180 and subtract both of the other values.

180 - 25 = 155

155 - 60 = 95

When two angles are supplementary, the sum of their angle measures equal 180, or a straight angle.

Using that information, take 180 and subtract 80.

180 - 80 = 100
