An underwater diver sees the sun 50 degrees above horizontal.

How high is the sun above the horizon to a fisherman in a boat above the diver?

2. Relevant equations

n΄sinθ΄ = n¹sinθ¹

or, if that is confusing,

n1sinθ1 = n2sinθ2

3. The attempt at a solution

I visualized it like this:

and using that, found the other angle (θ2, 'opposite' to x) as 90-50 = 40

so using the formula, i got this:

(1)sin(x) = 1.33 sin (40),

x =58.7485

computer says this is incorrect, any help? thanks
