Question

Find the value of x
A 41
B 44
C 46
D 36

Answer 1

This time it's cosine.

Cosine is the adjacent/hypotenuse. In this case, the adjacent is 15 and hypotenuse is 21.

15/21, or like 5/7.

Now put that into a fancy calculator with the
`cos^(-1)` thing or something like that and then you have the answer, or around 44 degrees.
