Use the Pythagorean theorem that will help you with A

thanks, what do i do for b?

Use the Pythagorean identity and if that does not work try the reciprocal identity.

the 3rd side is y=√(49-x^2)
Now just use the normal ratios to find the trig values.
sinθ = x/7
cosθ = y/7 = √(49-x^2)/7
tanθ = x/y = x/√(49-x^2)
that means that
θ = sin<sup><sup>-1</sup></sup> x/7
