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
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.
