Answer 1

X= 13

Another way to do it from the other answer is you know 5 goes into 20 4 times so you do 52 divided by 4 and you get 13.

Answer 2

48÷12=4

This gives you the enlargement of the smaller triangle to the bigger one. You just do the same for the missing side.

x*4 = 52

Rearrange that to get x on its own.

x=52/4

Therefore:

x=13
