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,

`(6)/(x) = (9)/(8)`.

On cross multiplication

6 * 8 = 9 * x .

48 = 9 *x

On dividing by 9 and switching sides.

x =
`(48)/(9)`.

x = 5 .33

x = 5.3

Therefore, D) x = 5.3 .

Answer 2

Cross multiply:

6 * 8 = 9*x

48 = 9x

x = 48/9

x = 5.3

The answer is D.
