Question

Write an equation that can be used to solve the problem. Find the solution to the problem. Angles A and B are complementary angles. Determine the measures of angles A and B if angle A is 8 times the size of angle B.

Answer 1

A = 80

B = 10

Explanation:

a + b = 90

a = 8b

above are the two equations that we will used to find A and B.

substitute in 8b for a in the first equation.

a + b = 90

8b + b = 90 Combine like terms

9b = 90 Divide both sides by 9

b = 10

If b is 10, than a must be 80.
