Your friend's house is 4 miles south and 7.5 miles east of the bank. How far is your friend's house to the bank?
You can use the pathagareom therom to help you solve this problem what a sec let me work this out
I believe the answer is 8.5
We can use the Pythagorean Theorem here.....the distance, d, is given by :
d = √ [ 4^2 + 7.5^2] = √ [ 16 + 56.25 ] = 8.5 miles
Just as HiylinLink found.....!!!
Oh good I was scared for a second there XD
