"Find the third angle of a right triangle if the measure of one on the angles is 10 degrees"
Angles of a triangle add up to 180.
If it is a "right triangle", then one angle is 90.
10 + 90 + x = 180 {added the two given angles with the missing angle, x, and set equal to 180}
x + 100 = 180 {combined 10 and 90}
x = 80 {subtracted 100 from both sides}
the third angle is 80
