The measure of an angle is 10 degrees more than 3 times its complement find the measure of the angle?

The complement means the angles add to 90. If the compliment is x the other angle is 3x+10 (10 more than 10 times the compliment) These two angles add to 90 x + 3x+10=90 4x+10=90 4x=90-10 4x=80 x=80/4 x=20
