Find the value of x, rounded to the nearest degreePlease explain how to find this. I know that it's sine/cosine ratios but I'm not sure hwo to set it up.

Hi there! The answer is x = 27.8

To find the length of RS we need to use the sine.
The general formula of the sine is the following
[tex] \sin(x) = \frac{opposite \: side}{hypotenuse} [/tex]


When we fill in the formula, we get the following
[tex] \sin(x) = \frac{7}{15} \\ x = \sin {}^{ - 1} ( \frac{7}{15} ) = 27.8[/tex]
