Question

LAST ATTEMPT IM MARKING AS BRAINLIEST!! (Finding missing sides- similar triangles Algebraic practice )

Answer 1

143 / 6x+12 = 132 / 72
143 / 6x+12 = 11 / 6

crossmultiply:
66x + 132 = 858
66x = 726
x = 11

Answer 2

Answer:

$\frac{vw}{gf} = \frac{uv}{hg}$

$\frac{72}{132} = \frac{6x + 12}{143}$

$\frac{6}{11} = \frac{6x + 12}{143}$

Now we cross multiply

6×143=11(6x+12)

858=66x+132

858-132=66x

726=66x

x=11
