Slowly tilt the level to find the plumb line, which will be where the bubble lines up in the exact center. In geometry, there are different types of angles such as acute, obtuse and right angles, which are under 180 degrees. The Full Circle. Right angles represent one-fourth of a full 360-degree revolution. It means turning around until you point in the same direction again. An acute angle falls somewhere between nonexistent and a right angle (see Figure 4). Slide 1 of 9: Right in their backyard! Since we know that each number on the clock is separated by 30 degrees, we can simply add 30 to 90 degrees and get 120 degrees for the angle at 4:00. 180 - x = 4 (90-x) (supplementary angles add together to make 180 degrees. Calculate the Angle between 12 and the Hour hand 10: Since there are 360 degrees in a full circle (clock), and there are 12 hours, each hour represents 360/12 = 30 degrees.
