Sums of Angles of Triangles

Lukas and Tyler are working on a math problem about triangles. They found a triangle where one angle measures 45 degrees and another angle measures 60 degrees. They are trying to figure out what is the measure of the third angle.

• The measure of the third angle is 30 degrees.

• The measure of the third angle is 75 degrees.

• The measure of the third angle is 90 degrees.

• The measure of the third angle is 100 degrees.
