    Take my advice: If @campbell_st tells an answer is correct, you can believe it's correct. A is the correct answer.

    you know that hypotensue is equal to x into sqrt2 as hypotenuse is given which is 12 |dw:1435961067163:dw|

    @Haseeb96 Perhaps you mean the ratio of the lengths of the sides is \(1 ~:~1~:~ \sqrt2\) That is true of a 45-45-90 triangle. This is not such a triangle, so you need to use the sine function.

    Also, if that were the case, x would be 8.49, not 11.85.
