Question

Solve for x please I can’t seem to know anything I feel so dumb please someone help me please

Answer 1

The triangles are similar

So, ratio of similar sides is equal

So,
`(x)/(9) =(12.5)/(10)`

To get the value of x , let us multiply by 9 on both sides

`9*(x)/(9) =9*(12.5)/(10)`

`(1x)/(1) =(12.5*9)/(10)`

x=
`(112.5)/(10)`

x=11.25 Option A

Answer 2

In this question, the two triangles are similar, so we have to use the similarity property of triangle which is

Corresponding sides of the similar triangles are in same proportion .

So we get

9/x = 10/12.5

Performing cross multiplication

10 x = 9*12.5

x = 11.25

So the correct option is the first option .
