Question

The triangles are similar.

What is the value of x?


Enter your answer in the box.

x =

Answer 1

x = 12

Explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

`(6x+28)/(25)` =
`(28)/(7)` = 4

Multiply both sides by 25

6x + 28 = 100 ( subtract 28 from both sides )

6x = 72 ( divide both sides by 6 )

x = 12

Answer 2

x=12

Explanation:

because they are proportional, the side should be 100 so you just solve from that equation for 100.
