Question

Find the length indicated

Answer 1

20

Explanation:

the scale factor from the little triangle to the larger triangle is 5/4

`(5x)/(4)` = x + 5 Multiple through by 4 to clear the fraction

5x = 4x + 20 Subtract 4x from both sides

x = 20

Answer 2

Answer: 20

Using the side splitter theorem yields:

`(?)/(5)=(12)/(3)\\\\(?)/(5)=4\\\\?=20`
