To find the size of angle x, subtract the given angle from 180 and divide the result by 2. To work out the bearing of A from B, measure the bearing angle using a protractor.

To calculate the size of angle x in the diagram, we can use the fact that the sum of the angles in a triangle is 180 degrees. Since we already know one angle is 82 degrees, we can subtract this from 180 to find the sum of the other two angles in the triangle. Then, divide this sum by 2 to find the measure of angle x.

For example:

Sum of the other two angles = 180 - 82 = 98 degrees

Measure of angle x = 98 / 2 = 49 degrees

To work out the bearing of A from B, we need to use the concept of bearing angles. The bearing of A from B is the angle starting from the north direction and going clockwise to the line connecting A and B. In this case, we can use a protractor to measure the bearing angle.

For example:

If the bearing angle is measured as 55 degrees clockwise from the north, then the bearing of A from B is 55 degrees.
