Question

Look at the picture please answer it.

Answer 1

r = 7

Explanation:

These two angles are complementary which means they add to 90. That's how you get a workable equation.

5r + 5 + 8r - 6 = 90 Combine like terms

5r + 8r + 5 - 6 = 90

13r - 1 = 90 Add 1 to both sides.

13r = 90 + 1

13r = 91 Divide by 13

13r/13 = 91/13

r = 7
