Step-by-step explanation:
Hope this helps!
Always get rid of denominators first. Multiply both right and left side by 6
-7 (6) = -c (6)/6 + 12(6)
-42 = -c + 72
c = 72 +42
c = 114
rearrange like terms together
42 = 18 - 4x
4x = 18 -42
4x = -24
divide both sides by 4
x = -6
Sin = opposite / hypotenuse so SinS = QR/68. You have to use Pythagorean Theorem to find QR.
