Question

Given: ABC is similar to XYC. If BY = 4, YC = 7, XC = 10. Which of the following proportions could be used to solve for AC? 4/7 = 10/AC 7/4 = 10/AC 4/11 = 10/AC 7/11 = 10/AC

Answer 1

The answer is D :)

Step-by-step explanation:

Answer 2

Answer: The correct option is 4th, i.e.,
`(7)/(11)= (10)/(AC)`.

Step-by-step explanation:

It is given that ABC is similar to XYC. If BY = 4, YC = 7, XC = 10.

Draw a diagram by using the given information.

From the figure,

`BC=BY+YC`

`BC=4+7`

`BC=11`

If the two triangles are similar then their corresponding sides are is in proportion and the corresponding angle are same.

`(YC)/(BC)=(XC)/(AC)`

`(7)/(11)=(10)/(AC)`

Therefore, the correct option is 4th.
