Answer:

x = 15in

Step-by-step explanation:

We can use the Pythagorean theorem to solve since this is a right triangle

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

9^2 + 12^2 = x^2

81 +144= x^2

225 = x^2

Take the square root of each side

sqrt(225) = sqrt(x^2)

15 =x

If you subtract the $9.60 from the $53.70 you would be taking out the tip which would be $44.10. Then if you divide the $44.10 by 2, because they both payed equally, you would get $22.05 per person, not including the tip.
