Answer 1

Triangle ABC is congruent to triangle DEF. In triangle ABC, side AB measures 13, side BC measures x+13, and side CA measures 16. In triangle DEF, side DE measures 13, side EF measures 3x−20, and side FD measures 16. What equation would help you to solve for the side length of BC and EF?

Answer 2

can someone show me how to solve this problem ? i dont wanna just know the answer

Answer 6

ABC and DEF are congruent. So
AB = DE = 13
CA = FD = 16 and
BC = EF
i.e x+13 = 3x−20
Solve this eqn for x and then calculate BC and EF.
Does this help ?

Answer 7

yes hold on

Answer 8

i cant even solve the equation

Answer 9

i get -7=2x

Answer 10

or -2x=-23

Answer 11

am i suppose to solve for x right ? @ShailKumar

Answer 12

Yes. solve for x.

Answer 13

-2x=-33

Answer 14

x+13=3x-20
+20 +20
x+33=3x
-x -x
33=2x

Answer 15

so like x is like 16.5

Answer 16

Right! Now calculate BC and EF

Answer 17

they both equal 29.5

Answer 18

That's right! They should be for they are congruent triangles.

Answer 19

my gosh thanks
man
