Option D

Step-by-step explanation:

SAS criterion- two sides and an included angle.

This means that we have

(i) AC = DE

(ii) ∠C = ∠D

(iii) the third should be another side so that there are 2 sides with an included angle.

Hence, it will be

BC = FE                     (Option D)

Hope this helps you!

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
