Question

Which expression shows the value of q? r cos 55° r sin 55° s over sin 55 degrees s over cos 55 degrees

Answer 1

Given:

`\text{Opposite side=}r\text{ ; adjacent side=}s\text{ ; hypotenuse side=q}`
`\cos \theta=\frac{adjacent\text{ side}}{\text{hypotenuse side}}^{}`
`\cos 55^(\circ)=(s)/(q)`
`q=(s)/(\cos 55^(\circ))`

4th Option is the correct answer.
