An air ambulance is travelling from Barrie to Toronto. Toronto is located 90 km [S5°E] of Barrie. If the wind is blowing from the South with a velocity of 62 km/h, and the plane’s air speed is 375 km/h, what direction must the pilot fly to make it to Toronto?

The answer is [S4.8°E] but I do not understand how to get to the answer

Thanks :)

Draw an angle in standard position whose terminal side contains the point 

Find the distance from the origin to this point.

Rectangle ACEF shown in the figure is a golden rectangle. It is constructed from square ACDB by holding line segment OB fixed at point O an then letting point B drop down until OB aligns with CD. The ratio of the length to the width in the golden rectangle is called the golden ratio. Find the lengths below to arrive at the golden ratio. (Let a = 1.)

(d) Find the ratio .
