Question

1. Find the value of x.

Answer 1

Answer:

x = 14

Step-by-step explanation:

Assuming the triangles are similar then the corresponding sides are in proportion, that is

$\frac{15}{x-4}$ = $\frac{12}{8}$ = $\frac{3}{2}$ ( cross- multiply )

3(x - 4) = 30 ( divide both sides by 3 )

x - 4 = 10 ( add 4 to both sides )

x = 14
