Question 985648: Find an angle which is 25 degree less than 4 times it complement
Answer by algebrahouse.com(1659)   (Show Source):
You can put this solution on YOUR website! Complementary angles add up to 90°
x = an angle
4x - 25 = its complementary angle
x + 4x - 25 = 90 {added the two angles and set equal to 90}
5x - 25 = 90 {combined like terms}
5x = 115 {added 25 to each side}
x = 23 {divided each side by 5}
4x - 25 = 67 {substituted 23, in for x, into 4x - 25}
23° and 67° are the two complementary angles
