JIMMY IS RIDING HIS SKATEBOARD. HE HAS BUILT A RAMP TO JUMP OFF. THE ANGLE OF ELEVATION OF THE RAMP IS 22° AND THE TOP OF THE RAMP IS 4 FEET OFF THE GROUND. How
LONG IS THE RAMP?

x = - √10, and x =√10

Step-by-step explanation:

1. Let us add 3 to either side of the equation: x^2 - 3 + 3 = 7 + 3

2. That equation would simplify to: x^2 = 10

3. Now let us take the square root on either side: √x^2 = √10

4. Being square root of x^2, we could say that: | x | = √10

5. And thus 2 answer may be derived from this equation provided absolute value symbol ( | | ): x = - √10, and x =√10
