Question

Solve for x in the diagram below.

Answer 1

Answer:

x = 9

Step-by-step explanation:

The parallel lines divide the sides of the triangle in proportion, that is

$\frac{20-8}{x}$ = $\frac{8}{6}$

$\frac{12}{x}$ = $\frac{8}{6}$ ( cross- multiply )

8x = 72 ( divide both sides by 8 )

x = 9
