What is the value of x? x = ___

Mathematics
1 answer:
iVinArrow [24]3 years ago
5 0

Answer:

x = 9

Step-by-step explanation:

The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion.

\frac{9}{81}=\frac{3x-20}{3x+36}

Cross multiply to solve for x.

9(3x+36) = 81(3x-20)

27x + 324 = 243x -1,620

1,944 = 216x

9 = x
