Using the same picture as the last problem, how far is the refreshment stand form the parking lot?  Round to nearest hundredth if necessary.

Let  the distance  from  the parking lot to the beach be  the altitude of the  triangle = A

 

We  have  this relationship

 

10 / A  =  A /12           cross-multiply

 

10 * 12  =  A * A

 

120  =  A^2

 

The distance  from the refreshment  stand to  the parking lot is

 

sqrt  [ A^2  + 12^2 ]   =    sqrt  [  120 + 144 ]  =  sqrt 264  ≈  16.25 m
