Answer:

Step-by-step explanation:
1. Regroup terms.

2. Add 1 to both sides.

3. Simplify 3x + 3 + 1 to 3x + 4.

4. Subtrect 3x from both sides.

5. Simplify 4x - 3x to x.

Therefor, the answer is, x = 4.
Sin(angle) = opposite leg / hypotenuse
Sin(45) = Opposite leg / 28
Opposite Leg = 28 * Sin(45)
Opposite Leg = 14 SQRT(2) = 19.8
A line parallel and passing through point (1,5) would be y=-3x+8
