Ok a little heads up I noticed with the dumb google calculator
tan(20 degrees) is actually equal to 0.36, not sure why google calculator was giving me that other number. But the steps are the same. So the first answer is actually something like 27. And yes you're answer looks right |

Oh, one more thing about trig real quick. If I want to find the angle of a right triangle, I know I need to use inverse sin, cos, or tan.
Walk me through the steps of finding the angle of a right triangle whose hypoteneus is 5 units, and whose opposite side is 7 units.

It's basically just the reverse, there's no steps involved, unless it was values used on 45-45-90 triangles or 30-60-90 Plus what skaltezon said LOL |

K. Disregarding the fact that my triangle is breaking all the rules, I would simply divide the opposite side by the hypoteneus and multiply that number by the inverse of sin? That works for me.

Well displacement is actually velocity over time (d = v/t) if I remember correctly, but that's one dimensional. The problem has both the x and y dimension, and is asking for the components of the vector, which the vector would be a diagonal line. I would need to figure out the x component and the y component that made the resultant vector.
