Calculating Angle AOS

To calculate the angle AOS, we can use the fact that the sum of the angles in a triangle is 180 degrees. Given that angle ABC is 120 degrees, we can find the angle AOS using the following steps:

1. Calculate Angle BAC: - Angle BAC is the same as angle ABC, which is given as 120 degrees.

2. Calculate Angle AOC: - Angle AOC is the sum of angles BAC and BOC. - From the given information, we can find that angle BOC is also 120 degrees. - Therefore, angle AOC = 120 + 120 = 240 degrees.

3. Calculate Angle AOS: - Angle AOS is the exterior angle of triangle AOC. - The exterior angle of a triangle is equal to the sum of the two opposite interior angles. - Therefore, angle AOS = 180 - AOC = 180 - 240 = -60 degrees.

So, the angle AOS is -60 degrees.
