By definition, complementary angles are two angles that add up to 90 degrees.
Therefore, we have the equation:
3x + (2x - 5) = 90
Combining like terms, we get:
5x - 5 = 90
Adding 5 to both sides, we get:
5x = 95
Dividing both sides by 5, we get:
x = 19
So, the two angles are:
3x = 3(19) = 57 degrees
2x - 5 = 2(19) - 5 = 38 - 5 = 33 degrees
Thus, the two angles are 57 degrees and 33 degrees.
What are the two angle measures of complementary angles expressed as 3x degrees and (2x-5) degrees?
