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}=\frac{s}{q}$$q=\frac{s}{\cos 55^{\circ}}$

4th Option is the correct answer.
