<PRE><B>Question 812597</B>
An airplane flies 200 miles from point A in the direction 115° and then travels in the direction 210° for 80 miles. 
Approximately how far is the airplane from A?
------
Assume A is the point (0,0)
-----
Assume the end point of travel is (x,y)
------
x-coordinate:: 200*cos(115)+80*cos(210) = -153.8
y-coordinate:: 200*sin(115)+80*sin(210) = 141.26
------
distance from A to (x,y) = sqrt[153.8^2+141.26^2] = 208.82 miles
