Seven pizzas: 7 pizzas
Shared between 3 friends: 7 pizzas / 3 friends
Simplify the fraction:
7 / 3
(3 goes into 7 twice, 7 - 6 = 1)
2 1/3
The fraction of pizza that each friend gets is 2 1/3.
Hope this helps!! :)

Answer:
42
Step-by-step explanation:
One angle of a regular pentagon = 108° 
One angle of a regular hexagon = 120°.
 One angle of a square = 90° 
∴ ∠BAC = 360 – (108 + 20 + 90) 360 – 318 = 42°
