Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

x = 10

Step-by-step explanation:

Since the triangles are similar the ratios of corresponding sides are equal

$\frac{20}{20+8}$ = $\frac{3x}{4x+2}$, that is

$\frac{20}{28}$ = $\frac{3x}{4x+2}$ ( cross- multiply )

20(4x + 2) = 84x

80x + 40 = 84x ( subtract 80x from both sides )

40 = 4x ( divide both sides by 4 )

x = 10
