Homework Statement
The pilot of an aircraft wishes to fly due west in a 50.0 km/h wind blowing toward the south. The speed of the aircraft in the absence of a wind is 205 km/h.
a.In what direction should the aircraft head?
b. What should its speed be relative to the ground?
Homework Equations
c^2 = a^2 + b^2
The Attempt at a Solution
for the degree, i got 13.7 but the answer is 14.1 north of west
tan^-1 = (50/205) = 13.7
for the speed, I did (-50) ^2 + (-205)^2 = c^2, but that didn't match the answer of 1.99km/h
