x = 5.3

The answer is D.

Answer 2

Answer:

D) x = 5.3 .

Step-by-step explanation:

Given  : Two triangles.

To find : .Find the value of x rounded to the nearest tenth.

Solution : We have given two similar triangle

By the property of similar ratio of sides are equal.

Then,

$\frac{6}{x} = \frac{9}{8}$.

On cross multiplication

6 * 8 = 9 * x .

48 = 9 *x

On dividing by 9 and switching sides.

x = $\frac{48}{9}$.

x = 5 .33

x = 5.3

Therefore, D) x = 5.3 .
