Question

Find the indicated side length by using Sin, Cos, and Tan.

Answer 1

So we are looking for side
`z` and we are given the length of hypotenuse (
`b=18`) and angle
`\zeta=60`.

The function I would use is sine.


`\sin(\zeta)=(z)/(b)`

If we solve for side
`z`:


`z=b*\sin(\zeta)`

Now fill in the data.


`z=18*\sin(60)\approx\boxed{15.59}`
