WHAT IS THE VALUE IF X???‼️‼️ HELP ASAP
MaRussiya [10]

The value of x is 40.

Solution:

Given ΔVDG and ΔVNG are similar triangles.

DG = 207, NQ = 138, GQ = 60, QV = x

To find the value of x.

In two triangles are similar, then the measures of the corresponding sides are in proportional to each other.

$\Rightarrow\frac{DG}{NQ}=\frac{GQ}{QV}

Substitute the given values.

$ \Rightarrow\frac{207}{138}=\frac{60}{x}

Do cross multiplication, we get

$ \Rightarrow{207\times x}=138\times60

$ \Rightarrow{207\times x}=8280

Divide by 207 on both sides of the equation, we get

$ \Rightarrow x=\frac{8280}{207}

$ \Rightarrow x=40

Hence the value of x is 40.
