    hint ...we have an angle....and we have sides opposite to that angle...and the hypotenuse correct? what trig function uses opposite and hypotenuse?

    you can use the trig function sin.

    exactly as @Hope_nicole has said....sin is opposite/hypotenus correct? so we have sin(x) = 11/17 we dont know x right? so we need to use the inverse sin to find this answer \[\sin^{-1} 11/17\] this will give you your x...just do 11/17...then inverse sin...of that answer

    you have a calculator correct? instead of just hitting sin...hit "2nd" (probably a blue or yellow button in the top left hand side" then hit sin...that should be sin^-1

    you hit the second button your calculator and then hit the sin button.

    *****************remember to have your calculator in DEGREES mode and not RADIANS mode*********** :) that's a VERY common mistake

    the second button is going to be in the very top on the left.

    there's shift, const, eng, mode, copy, and off at the top. No 2nd

    then it would be shift, right @johnweldon1993

    so shift...then sin...you should see \[\sin^{-1} \] pop up
