Please help How to calculate cos (x)=\frac{6}{15}? I'm doing a trig question; trying to find angle XYZ, and I think the formula for the answer is C = \frac{A}{H}, which as stated in the title, I think in this situation is Cos(x)=\frac{6}{15}.

I don't know what I'm doing wrong, or if I've done the whole question wrong, but no scientific calculators will give me an answer because it says Cos is already defined. I know for sure the answer isn't 0.4, which was a guess I made. The entire question is attached below.
