I honestly don't know this but if you got the second option at least explain

KingPizza · Answer

I'm starting to doubt that's it's the second option because I'm testing it

xxemilianaxx · Answer

Well, Then do that, Test them untill you find the one that fit's.

KingPizza · Answer

I tried, but neither of them worked, that's kind of weird I messed up somewhere I just don't know where

KingPizza · Answer

well I'm thinking the answer may be A

GoodFellow · Answer

$$\begin{aligned}cosA &= \frac{b^2+c^2-a^2}{2bc}=\frac{3^2+6^2-4^2}{2\times3\times6}=0.806 \A&=\cos^{-1}(0.806)\&\approx36^0 \end{aligned}$$

GoodFellow · Answer

Try others

KingPizza · Answer

well then it would have to be B since that is the only option for 36 degrees for the A value
