The terminal side of an angle theta goes through the point (-5, -12) find sin theta, cos theta, and tan theta.

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

well what did you do it matters what you did : )
