Question

A pair of congruent angles are described as follows: One angle measures nine more than six times a number, and the other angles described as being thirty less than nine times a number. What is the measure of the angles in degrees?

Answer 1

87 degrees

Explanation:

congruent means equal to set each expression equal to each other:

9 + 6n = 9n - 30

39 = 3n

n = 13

substitute 13 into each expression; make sure they are both equal
