SOLUTION: If the measure of one angle is 3x and the measure of its complement is 2x, what is the value of x?

Question 419862: If the measure of one angle is 3x and the measure of its complement is 2x, what is the value of x?

Two angles are considered complements if their measurements add up to 90 degrees. The sum of your two angles is 3x + 2x which must equal 90 for the angles to be complementary.
3x + 2x = 90
5x = 90 (combining like terms)
x = 18 (dividing both sides by 5)
The answer is x = 18.
Let's check the answer: If x = 18, then the first angle has a measurement of 3x = 3 * 18 = 54; the second angle has a measurement of 2x = 2 * 18 = 36. Since 54 + 36 = 90, the angles are complementary.
