step 2: Chris added the exponents when he should have multiplied them
A is 95t+25. This is the simplest form, but the way you do it is that 25t+15+20t+10+50t=9t+25.
A/7 + 5/7 = 2/7
1/7a + 5/7 = 2/7
1/7a + 5/7 - 5/7 = 2/7 - 5/7
1/7a = -3/7
7*(1/7a) = 7*(-3/7)
a = -3
The third angle: 180° - 90° - 51.5° = 48.5°
