<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>
Answer:
7 units

Hey there!
ax + 7 = 8x + b
when x=9, so:
a(9) +7= 8(9) +b
9a +7= 72+b

2
add 6 to both sides and it becomes 4c=8 divide 4 by both sides and it becomes c=2
