Question

plz help

Answer 1

start by solving for x

AD has a length of 2x + 20 but you are told AD = 40

so 2x + 20 = 40 then x = 10

now triangles ABG abd ACF are similar by angle angle postulate

so using the ratio of corresponding sides

AB = 10 and AC = x + x + 10 or 30

then

\[\frac{BG}{39} = \frac{10}{30}\]

solve for BG

Answer 2

is it 13

Answer 3

that would be my answer

Answer 4

ok

Answer 5

so what is the perimeeter

Answer 6

well you know the value of x... so that should make it easy...

Answer 7

can u tell me

Answer 8

no....

the last part is uses the ratio of corresponding sides in similar triangles.
