Question

The measure of one angle of a triangle is 55 degrees. The measure of the third angle is 20 degrees more than twice the second angle. All three angles of a triangle must add to 180 degrees. Find the measures of the second and third angels.

Answer 1

If 1 angle is 55 and another is 55 add 20 (75) if you added them together it would be 130 so do 180 - 130 hope this helped!!
