Answer 1

Answer:

The total of a clock’s angles is 360 degrees.

If we divide that by 12 (to find the degree for every hour), we get:

360/12 = 30

Now, if we multiply that by 4 (to find the angle at 4 o’clock), we get the answer which is:

30 * 4 = 120

——————

We can also do that in another way, since 4 o’clock represents 1/3 of a clock’s angles:

360 * 1/3 = 120
