    \[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\]

    first apply Pythagorean theorem to find 3rd side

    tan = opposite over adjacent so nope 17 is a hypotenuse

    hypotenuse is the longest side |dw:1432869486567:dw|

    you have to use Pythagorean theorem to find 3rd side

    nope that's an angle you have to find the length of adjacent side do you know the Pythagorean theorem ?

    a^2+b^2=c^2?? @Nnesha

    yes right plug in 2 sides of right triangle and find 3rd side :-)

    so 8^2+17^2=x^2?? @Nnesha

    C is the longest side of right triangle which is hypotenuse so replace C by 17

    OH. okay so 64+x^2=289 -64 -64 x^2=225 x=15 @Nnesha
