Answer:
The measure of the third angle is 75 degrees.
Step-by-step explanation:
We know that the total angles of a triangle must equal 180 degrees. If we know two of the angles, we must add them together, then subtract them from 180. 45 + 60 = 105, 180 - 105 = 75. The measure of the third angle is 75 degrees.
Answer:
Step-by-step explanation:
2{5x²-15+(-9xy²)}-(2y²+4x-xy²)+3x²
=2{5x²-15-9xy²}-(2y²+4x-xy²)+3x²
=10x²-30-18xy²-2y²-4x+xy²+3x²
=13x²-2y²-17xy²-4x-30
