Give these answers both as an exact answer in the most simplified form and as decimals rounded to the nearest hundredth. Answer by rfer(16322) (Show Source):
You can put this solution on YOUR website! a^2=c^2-b^2
a^2=10^2-3^2
a^2=100-9
a^2=91
a=9.54 ft
----------------
chart the direction and find he is 2 min so and 4 mi east of starting point
c^2=a^2+b^2
c^2=4^2+2^2
c^2=16+4
c^2=20
c=4.47 miles
