Could someone help me really quick!

Answer 1

A is the answer to the problem

Answer 2

The triangles are similar triangles, so the proportion of the corresponding sides are the same.

Make a comparison.

`\frac{\text{hypotenuse}}{\text{upright side}} = \frac{\text{hypotenuse}}{\text{upright side}}`

In this case, you can input the numbers as follows.

`(x)/(2)= (54)/(12)`

Solve for x
Move 2 to the right side, and 2 will be a numerator
x =
`(54(2))/(12)`
x =
`(108)/(12)`
x = 9

The value of x is 9, the answer is first option
