Suppose ABCD is a rectangle, F and G are points on DC

such that

DF = GC, and

A(F) ∩ BG = E. Prove that DE = CE.

(I had to put parentheses around the F or else would think I'm swearing, just so you know.)

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
