Answer:

<em>x = 15</em>

Step-by-step explanation:

When figures are similar, the lengths of corresponding sides are in the same ratio.

In the figure, the side measuring 8 corresponds to the side measuring 20. The ratio of the lengths of those two corresponding sides is 8/20.

The side measuring 6 corresponds to the side measuring x. The ratio of the lengths of those two corresponding sides is 6/x.

Since the quadrilaterals are similar, the ratio 8/20 must equal the ratio 6/x.

We use that fact to write an equation, and then we solve for x.

8/20 = 6/x

Reduce the fraction on the left side.

2/5 = 6/x

Cross multiply.

2x = 5 * 6

2x = 30

x = 15

Given the lengths of two sides of a triangle, find the range for the length of the third side. (Range means find between which t
Sidana [21]
<h3>Answer:  5 < x < 21</h3>

Explanation:

Let x be the length of the third side. We can't find the exact value of x, as we don't have enough info, but we can find possible values for x.

The lower boundary for x is 13-8 = 5. It must be larger than this value.

At the same time, x must be smaller than 13+8 = 21 as well.

So x > 5 and x < 21 becomes 5 < x < 21

In short, x is between 5 and 21. It cannot equal either endpoint.
