Question 907108: Find the measure of an angle if five times the measure of its complement is 24 degrees less than twice the measure of its supplement.
This is what I have: 5 (90-x)=2 (180-x)-24 but I can't get a positive answer. Can you help?

5 (90-x)=2 (180-x)-24
450-5x=360=2s-24
90=3x-24
114=3x
x=38

Step 1. Two angles are complementary when they add up to 90 degrees and two angles are supplementary when they add up to 180 degrees

Step 2. Let x be the angle.

Step 3. Let 90-x be the complementary angle.

Step 4. Let 180-x be the supplementary angle.

Step 5. Let 5%2890-x%29 be five times the complement of the angle.

Step 6. Let 2%28180-x%29 be twice the measure of its supplement

Step 7. Let 5%2890-x%29=2%28180-x%29-24 since five times the measure of its complement is 24 less than twice the measure of its supplement
)
Step 8. Then solving the equation of Step 7 5%2890-x%29=2%28180-x%29-24 will lead to the following steps:

5%2890-x%29=2%28180-x%29-24 ....solve for x
450-5x=360-2x-24
450-5x=336-2x
450-336=5x-2x
114=3x
114%2F3=x
38=x


So x=38 and 90-x=52 and 180-x=142.

Check...5%28x-90%29=2%28x-180%29-24 if true than 5%2A52=2%2A142-24 =>260=260 which is a true statement.

ANSWER:
The angle is 38 degrees, its complementary angle is 52 degrees and its supplementary angle is 142 degrees.
