<span>Two </span>Angles<span> <span>are </span></span>Complementary<span> <span>when they add up to 90 degrees (a Right </span></span>Angle). They don't have to be next to each other, just so long as the total is 90 degrees.

So (5x + 4) + ( 7x + 2) = 90

12x + 6 = 90

12x = 90 – 6

12x = 84

<span>X = 7</span>
