Can someone help me on this?
OverLord2011 [107]

Given:

\Delta DE F\sim \Delta DST

DE=40, EF=4x-4,DS=10,ST=11

To find:

The value of x.

Solution:

We have,

\Delta DE F\sim \Delta DST

The corresponding sides of the similar triangles are proportional.

\dfrac{DE}{DS}=\dfrac{EF}{ST}

On substituting the given values, we get

\dfrac{40}{10}=\dfrac{4x-4}{11}

4=\dfrac{4x-4}{11}

Multiply both sides by 11.

4\times 11=4x-4

44=4x-4

Add 4 on both sides.

44+4=4x

48=4x

Divide both sides by 4.

\dfrac{48}{4}=x

12=x

The value of x is 12. Therefore, the correct option is D.
