The compass heading is 135 degrees.
Calculating the bearing of an object using compass.
The compass is a small device that can be use to detect the location of an individual or an object in the four cardinal direction.
So, if the car travels in the direction of 45° degrees east of south, it means that from the south direction to east, the distance covered is 45° degrees.
On the compass bearing, North is 0 degrees, South is 180 degrees, East is 90 degrees, west is 270 degrees.
If the car travels in the direction east of south, then the compass heading is:
= 180 degrees - 45 degrees
= 135 degrees
