Answer 4

Since this is a right triangle, you can apply the basic definitions of trigonometric functions.
By the definition of cosine, cos theta = adjacent / hypotenuse.
cos 55 = x / 15000
Now, just solve for x.
x = 15000 cos 55

Answer 5

so what would it be

Answer 6

tukitw is right :)
just plug in 15000 cos(55) into your calculator
