We have to calculate the length of the missing side.
Use the Pythagorean theorem:

$a^2+32^2=58^2\\\\a^2+1024=3364\ \ \ |-1024\\\\a^2=2340\to a=\sqrt{2340}\\\\a=\sqrt{36\cdot65}\\\\a=6\sqrt{65}$

$\cos x=\dfrac{6\sqrt{65}}{58}=\dfrac{3\sqrt{65}}{29}$

I think. Your answers to choice are wrong.

Readme [11.4K]

We know that
[surface area of sphere]=4πr²
[surface area of hemisphere]=2πr²

(sphere)
r=12 in
[surface area of sphere ]=4π12²--------> 576π in²

(hemisphere)
r=12 in[surface area of hemisphere ]=2π12²--------> 288π in²

[the ratio of the surface area of sphere to the surface area of hemisphere]
=576π/288π-------> 2

the answer is
the ratio is 2
