Answer:
Step-by-step explanation:
Our problem reduces to the following. Given D = 65 miles, what is the length of the missing side? Let us call the missing side x
To find out the length of the missing side, we use pythogoras' theorem.
Since we know that D = 65, the above becomes
taking the square root of both sides gives
which we evaluate to get: upon using a calculator.
rounding to the nearest mile gives
which is our answer!
