If two angles are complementary, their measures add up to 90 degrees.
So, we can set up the equation:
3x + (2x-5) = 90
Combining like terms, we get:
5x - 5 = 90
Adding 5 to both sides:
5x = 95
Dividing both sides by 5:
x = 19
So, the measures of the two angles are:
3(19) = 57 degrees
and
2(19) - 5 = 33 degrees
What are the two angle measures of complementary angles expressed as 3x° and (2x−5)° ?
