Answer:

4

Step-by-step explanation:

Because the two trapezoids are similar, we need to find out what multiplied by 15 gets us to 6.

When a number is decreased by 16% of itself the result is 159.6. What is the number?
Rufina [12.5K]

Hey there! I'm happy to help!

Let's call this number n. Here is the info we can write about it. Remember that to write as a percent as a decimal you divide by 100.

n-0.16n=159.6

We combine like terms.

0.84n=159.6

We divide both sides by 0.84

n=190

Have a wonderful day! :D
