Cosine of the angle is equal to Adjacent/Hypotenuse, so it should be:

Answer 3

Now solve for 'x'.

Answer 4

don't still get 8.0292

Answer 5

What?

\(\sf x=\dfrac{12}{cos(48^o)}\)

Answer 6

What do you get when you simplify the right-hand side?

Answer 7

don't find the degree of 48 which is 0.6691 and multiple that with 12

Answer 8

so is my answer right?
