Please help, x = ? thank you!

x = 9.8

Step-by-step explanation:

They are same shape so we just get the ratio.

AB/JK = BC/KL

5 / 7 = 7 / x

5x = 49

x = 9.8

9.8

Step-by-step explanation:

This is a question that requires you to use ratios and proportions. The quadrilaterals that you have shown in the picture are similar, meaning that they share similar ratios and proportions. Thus, we can assume this:

- 5:7

- 3:4.2

- 2:2.8

- 7:x

To solve for x, we can just take any other ratio and equal it to the 7:x ratio. I'll take 5:7 for example.

, which can also be rewritten as

Let's solve for x by cross-multiplying numbers that when a straight line is made, they are real numbers, and then divide.

Here, it should be:

The answer should be 9.8.

power property.

answer: 193
