Answer:
8mi
Step-by-step explanation:
Using Pythagoras theorem
Hypotenuse square = opposite square + adjacent square.
Let the other leg be x
10 square = 6 square + x square
100 = 36 + x square
Collect like terms
X square = 100 -36
X square = 64
Find square root of both sides
X = square root of 64
X =8mi
