b = 10 + 7 a
a = 90-b
a = 90 - 10 - 7 a
8 a = 80

complementary angles sum to 90º
a + b = 90º ... a = 90º - b
a = 7 b + 10º ... substituting ... 90º - b = 7 b + 10º
solve for b , then substitute back to find a
a + b = 90º ... a = 90º - b
a = 7 b + 10º ... substituting ... 90º - b = 7 b + 10º
solve for b , then substitute back to find a
