7 0

This is a 30-60-90 triangle, so the hypotenuse is twice as long as the short leg. The short leg is opposite the 30 degree angle.

hypotenuse = 2*(short leg)
AB = 2*BC
AB = 2*6
AB = 12

Step-by-step explanation:

This can be solved by working backwards.

7 is one more than half the number of invitations.

Double.

12 is the full number of invitations.

Algebra (if you must!):

x/2 + 1 = 7

Subtract 1.

x/2 = 6

Multiply by 2.

x = 12
