Triangle fox is transformed using a rotation. which could be coordinates of f'o'x' after the rotation? a) f=(1,1), o=(3,2), x=(0,3) b) f = (1, 1), o = (-3, -2), x = (0, -3) c) f=(1, -1), o=(3,-2), x=(0,-3) d) f=(-1,1), o=(-3, 2), x=(0,3

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

r and t.

both are 64 degrees.

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
