To find the two angle measures of complementary angles, we set up the equation:
3x + 2x - 5 = 90
Combining like terms, we get:
5x - 5 = 90
Adding 5 to both sides, we have:
5x = 95
Dividing both sides by 5:
x = 19
To find the two angle measures, we substitute x = 19 into the expressions:
3x = 3(19) = 57
2x - 5 = 2(19) - 5 = 38 - 5 = 33
So, the two angle measures are 57 degrees and 33 degrees.
The correct answer is A) 33 and 57.
