Value of x is x=16

Step-by-step explanation:

We are given two similar triangles and we need to find x.

Two triangles are similar, if their sides are in proportion and their angles are congruent.

Sides are proportional:

$\frac{8}{x}=\frac{12}{24}$

Solving the proportion to find value of x

Cross multiply

$24*8=12*x\\192=12x\\=> x=\frac{192}{12}\\x=16$

So, value of x is x=16
