"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°

Hi,

Angle 1 and 2 are complementary . If angle 1 = 3x and angle 2 = 2x. 

  3x + 2x = 90°

     5x = 90°

      x = 18°     Angles are 54°  and 36°
