Frosty lost the magic numbers from his hat. Help him find the numbers so his hat can be magical again in time for the party

The question is an illustration of an equilateral triangle.

From the complete question, the complete side of the triangle contains the following numbers:

1, 6 and 2.

The sum of these numbers represent the side length

On the base of the triangle, the numbers are 1 and 3.

So, the number that completes these set of numbers is 5.

This is so because, 5 added to the sum of 1 and 3 is 9

Lastly, the numbers on the last side of the triangle are 2 and 3.

So, the number that completes these set is 4.

This is so because, 4 added to the sum of 2 and 3 is 9
