Question 466016
"Angle 1 and 2 are complementary . If angle 1 = 3x and angle 2 = 2x. What is the measure of angle 1?"


Complementary angles add up to 90°


angle 1 = 3x
angle 2 = 2x


3x + 2x = 90 {the two angles add up to 90°}
5x = 90 {combined like terms}
x = 18 {divided both sides by 5}


angle 1 = 3x
= 3(18) {substituted 18, in for x, into 3x}
= 54°
