The triangles are similar by the aa similarity postulate. find the value of x. round you answer to the nearest tenth

 The required value of x is 7.5.

Step-by-step explanation:  Given that the triangles shown in the figure are similar by AA similarity postulate.

We are to find the value of x.

We know that the corresponding sides of the similar triangles are proportional.

From the figure, we see that two pairs of corresponding sides in the triangles are (4.5, 3) and (x, 5).

Therefore, we must have

Thus, the required value of x is 7.5.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
