Homework Statement
A plane flies from base camp to lake A, a distance of 280km, at a direction of 20 degrees north of east. After dropping thr supplies, it flies to lake B which is 190km and 30 degrees west of north from lake A. Determine the distance and direction gtom lake B to the base camp
Homework Equations
Axcos theta
Bysin theta
r= Sq rt (X^2 + y^2)
tan - theta = y/x
The Attempt at a Solution
280 cos 20 = 263
280 sin 20 = 95.8
190cos -30 = 184.5
190sin -30 = -95
I tried to add up the components but it doesn't end up being the rigth answer from the book.
