Answer:
3rd one
Step-by-step explanation:
they already have two red cards and the box of n cards was divided equally among 4 people
using pythagorean theorem
a^2 + b^2 =c^2
a^2 +8^2 =14^2
a^2 +64 = 196
subtract 64 from each side
a^2 = 132
take the square root of each side
a^2 = sqrt (132)
a=11.48912529
a =11.5
