Question
A Plane flies north at 215 km/h. A wind from the east blows at 69km/h. What is the plane's new velocity with respect to the ground in standard position

X = -69 km/h
Y = 215 km/h
Tan Ar = Y/X = 215/-69 = -3.11594
Ar = -72.21o = Reference angle.
A = -72.21 + 180 = 107.8o
V=Y/sinA = 215/sin107.8=225.8km/h[107.8]
Y = 215 km/h
Tan Ar = Y/X = 215/-69 = -3.11594
Ar = -72.21o = Reference angle.
A = -72.21 + 180 = 107.8o
V=Y/sinA = 215/sin107.8=225.8km/h[107.8]

Henry... where did you get the reference angle from? -72.21??

Why Vx is negative (-69km/h)
