Question

The triangles are similar.

Answer 1

5×4=20 , 12×4=48
53÷4 = 13 then
x=13

Answer 2

Answer : The value of x is, 13

Step-by-step explanation :

As we know that when two object have same shape then they are similar. That means, when two triangles are similar then their ratios of lengths of their corresponding sides are equal.

Let the name of the big triangle be, PQR and small triangle be, XYZ.

Given:

PQR is similar to triangle XYZ. That means,

$\frac{PR}{PQ}=\frac{XZ}{XY}$

$\frac{52}{48}=\frac{x}{12}$

x = 13

Therefore, the value of x is, 13
