Question

Two angles are supplementary. One of the angles measures (9n) degrees and the other angle measures (3n) degrees. a) what is the value of n? and b) what is the value of each angle measure?

Answer 1

a) n = 15

b) 9n = 135, 3n = 45

Explanation:

If the two angles are supplementary, the add up to 180. Solve using the equation (9n) + (3n) = 180:

9n + 3n = 180

12n = 180

n = 15

9n = 135

3n = 45
