A plan takes off from Chicago’s O’Hare Airport on runway 2 LEFT, which has a bearing of N20degreesE. After flying for 1 mile, the pilot of the plane requests permission to turn 90 degrees and head toward the northwest. The request is granted. After the plane goes 2 miles in this direction, what bearing should the control tower use to locate the plane?

A bearing is an angle measured clockwise from north, east being 090, south being 180 and west being 270 degrees. To solve this you need to use trigonometry. You first use pithagoras theorm to complete the triangle which makes root 5. you next use the sin to find the angle which can then be translated into a bearing. This is 26.56, now we have the whole triangle we can find the bearing which is 64.44, minus 20 is 44.44 and now take that away from 360 is:
N 315.56 degrees E
Theres your answer
I study A level maths
