Question

This pair of figures is similar. Find the missing side.​

Answer 1

Answer:

12

Step-by-step explanation:

Since 10x4=40, and 14x4=56, then all you have to do is multiply 3 by 4, to get 12.

Answer 2

Answer:

x = 12

Step-by-step explanation:

If given figures are similar, then corresponding sides are in proportion.

Therefore we have the equation:

$\dfrac{x}{3}=\dfrac{56}{14}$           cross multiply

$(14)(x)=(3)(56)$

$14x=168$            divide both sides by 14

$\dfrac{14x}{14}=\dfrac{168}{14}$

$x=12$
