Welcome to PF.

Can you be a little more specific?

#### Nick Leeson

I am given a problem that states the perpendicular weight is 390 and the parallel weight is 330 and it ask to find the weight or force of gravity and the angle of the incline. I know that the perpendicular weight is equal to mgsine theta, and the parallel weight is mgcosin theta.

Since they are vectors, then won't the ratio of the two be an expression of θ ?

Then just take the inverse to find θ .
