Application Giovanni is flying his Cessna airplane on a heading as shown. His instrument panel shows an air speed of 130 mi/h. (Air speed is the speed in still air without wind.) However, there is a 20 mi/h crosswind. What is the resulting speed of the plane?

x component = 130
y component = 20
speed = sqrt (130^2 + 20^2)
direction
tan angle up from x = 20/130
