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.

Part A:

My number line spans from -4 to 4. -4 is on the leftmost side while four is on the right. 0 is in the middle of all the numbers. On the tick mark number -3 there is a dot labeled Cheryl. 1/4 to the right o the -3 is another marking with the name John. To the right of the 0, there is the 3, on the tick mark for the three there is a mark that has Andrew on it.

Part B:

Cheryl owes more money than John does.

-$3.00 > -$2.75

|a| -$3.00 = $3.00

|a| -$2.75 = $2.75
