Answer: 10 degrees
Step-by-step explanation: All three angles in a triangle must add up to 180, so if you have the measure of two of those angles, you can figure out the measure of the last by setting either of the following equations:
106 + 64 = 170
180 - 170 = 10
or
106 + 64 + x = 180
170 + x = 180
x = 10
