because it is a right triangle and the angle & side are congruent, you know that BC and FE are the same.

huh? it wants the length.

right. it gives you the length of each side. so you need to solve for x, then plug in x, and you will find the length of BC!

because it is a right triangle, and AC=DF, and angle B=angle E, THEN you know that BC=FE. or, 3x+2=4x-6.

I know all of that, I just forgot how to actually solve 3x+2=4x-6
anonymous
  • anonymous
3x+2=4x-6 (3x+2)-3x=(4x-6)-3x 2=x-6 (2)+6=(x-6)+6 8=x

now plug in x to BC

B?????

nope! you're not done just yet. BC = 3x+2 x=8 therefore........answer is........?
