Answer:

BD = 2.2 cm

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{AB}{CD}$ = $\frac{BC}{DE}$ , substitute values

$\frac{2.4}{CD}$ = $\frac{1.0}{0.5}$ ( cross- multiply )

CD = 1.2

Thus

BD = BC + CD = 1 + 1.2 = 2.2 cm

Use the diagram.<br> What is the length of }EG ?<br> A 1 B 4.4<br> C 10 D 16

nataly862011 [7]

Answer:

Option (D)

Step-by-step explanation:

Length of the bar EG = 1.6x

If F is a point on the bar such that,

EF + FG = EG

Measure of segment EF = 6

Measure of FG = x

By substituting measures of each side,

6 + x = 1.6x

1.6x - x = 6

0.6x = 6

x = 10

Length of EG = x + 6

= 10 + 6

= 16 units

Option (D) will be the correct option.
