Question

Can someone please explain HOW you solve this problem. Solve for X

Answer 1

31.97

Explanation:

Apply the law of sines on the triangle: We know
`sin(\pi /2)`=1, so putting this in, We get
`9/sin(x)=17/sin(90)=17`. Now, solving for sin(x), we get
`sin(x)=9/17`. Taking the inverse,
`x=arcsin(7/19)`, which makes x approximately 31.97 degrees.

Alternatively, you could use the law of cosines to find the 3rd side, and solve for x in that fashion.
