Answer:

See below

Explanation:

to figure out the ratios we must figure out the length of hypotenuse first to do so we can consider Pythagoras theorem given by


\displaystyle {a}^(2) + {b}^(2) = {c}^(2)


\displaystyle \implies c = \sqrt{ {a}^(2) + {b}^(2) }

substitute:


\displaystyle c = \sqrt{ {12}^(2) + {9}^(2) }

simplify squares:


\displaystyle c = √( 225 )

simplify square root:


\displaystyle c = 15

now recall that,


  • \displaystyle \sin( \theta) = (opp)/(hypo)

  • \displaystyle\cos( \theta) = (adj)/(hypo)

  • \displaystyle \tan( \theta) = (opp)/(adj)

the ratios with respect to angle w given by


  • \displaystyle \sin( W) = (12)/(15) = (4)/(5)

  • \displaystyle \cos(W) = (9)/(15) = (3)/(5)

  • \displaystyle \tan( W) = (12)/(9) = (4)/(3)

the following ratio with respect to angle X


  • \displaystyle \sin(X) = (9)/(15) = (3)/(5)

  • \displaystyle \cos(X) = (12)/(15) = (4)/(5)

  • \displaystyle \tan( X) = (9)/(12) = (3)/(4)
