X = 12.7sin38°
(This should be typed into a calculator - it’s the equation)
Remember the differences between sine, cosine, and tangent
If you set up the equation of:
sin theta = opposite / hypotenuse
You get sin38° = x / 12.7
You are trying to find x so multiply both sides by 12.7
* x is the opposite side because it is across from the angle given
