Question 414251: two angels are complementary if their sum is 90 degrees. find the measure of each angle if the second angle is twice the first. (let first angel =x) Answer by algebrahouse.com(1659) (Show Source):
You can put this solution on YOUR website! "two angles are complementary if their sum is 90 degrees. find the measure of each angle if the second angle is twice the first. (let first angle = x)"
x = first angle
90 - x = 2nd angle {the two angles add to 90}
90 - x = 2x {the second is twice the first}
90 = 3x {added x to both sides}
x = 30 {divided both sides by 3}
90 - x = 60 {substituted 30, in for x, into 90 - x}
