Complimentary angles add up to 90º

So translate the English into Math.

if you let the unknown angle be x

then "the measure of the compliment of the angle" -----> 90-x

"10 degrees less than three times the measure of the angle" ----> 3x - 10

so....... 90-x = 3x - 10

solve that

The measure of the complement of an angle is 10 degrees less than three times the measure of the angle. Find the measure of the angle and its complement.
