Find the missing Side lengths.

{ Answer(s) }
Left side of big triangle (X & Y) : 15
Bottom side of big triangle (Y & Z) : 20
{ Explanation }
We know the top sides of both triangles. To find out how many units they are separated by, we need to divide 5 by 25.
25 / 5 = 5
Now we can continue.
3 * 5 = 15
4 * 5 = 20
The missing sides are 15 and 20.
