Question

Two measures of two angles of a triangle are 68° and 70°. Explain how to find the measure of the third angle.

Answer 1

Answer:

42*

Step-by-step explanation:

Each triangle's angles in sum give 180 degrees. From here we add 68 and 70 to get 138, then subtract 138 from 180 to get 42, and that would be the third angle.

Tell me if I'm wrong :)
