We know that two angles are complementary if their sum is equal to 90°.
So, we can set up the equation:
3x + (2x - 5) = 90
Combine like terms:
5x - 5 = 90
Add 5 to both sides:
5x = 95
Divide both sides by 5:
x = 19
Now we can substitute this value of x back into the expressions for the angles:
3x = 3(19) = 57
2x - 5 = 2(19) - 5 = 38 - 5 = 33
Therefore, the two angle measures of complementary angles are 57° and 33°.
The answer is: 33° and 57°.
