Question

The measure of angle A is 50⁰ and is complementary to the measure of angle B. If the measure of angle B is 5x-5 , what is the value of x ?

Answer 1

x=9

Explanation:

complementary angles equal 90 degrees. The equation would be 5x-5+50=90. Solve for X by subtracting 50 from both sides and adding 5 to both sides and you get 5x=45 then you divide by 5 and get x=9
