Question

Find the measure of the third angle of a triangle given that the first two angles are 44º and 72º.

Answer 1

The sum of the three angles of a triangle need to equal 180

To find the third angle subtract the two known angles from 180.

Third angle = 180 - 44 - 72 = 64 degrees.

Answer 2

Answer:

All angles of a triangle add up to 180. Just subtract. -72 --> 108 - 44. 64
