These triangles are similar. Find the missing side of the large triangle, then, find the PERIMETER of the large triangle.

• the missing side is 12, the perimeter is 24

• the missing side is 12, the perimeter is 36

• the missing side is 10, the perimeter is 34

• the missing side is UNKNOWABLE!, the perimeter is A MYSTERY!
