To Prove :
Side lengths 6, 8 and 10 will make a right triangle.
Solution :
We know, by Pythagoras theorem :

Here, c is the biggest side and a and b are other sides.
Putting given values in above equation.

Since, LHS = RHS .
Therefore, lengths 6, 8 and 10 will make a right triangle.
L= R x angle = 7 x 2 = 14
Bell:
1 hour = 10 miles
4.5 hours = 10 x 4.5 = 45 miles.
Kristin:
1 hour = 14 miles
4.5 hours = 14 x 4.5 = 63 miles
Difference in distance = 63 - 45 = 18 miles.
Answer: They will be 18 miles apart.
