You start driving west for 3 miles, turn right, and drive north fer another 13 miles. At the end of driving, what is your straight line distance from your starting point?
Round to the nearest tenth of a mile.

13.3 miles

Step-by-step explanation:

So you're driving < for 3 miles

Then you start driving up for 13 miles

This makes a right triangle with sides of 3 and 13

using pathagoreas, a^2+b^2=c^2

3^2+13^2=c^2

9+169=c^2

178=c^2

Square root both sides

c= 13.3416640641

Rounding, it's 13.3 miles

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
