WebMar 3, 2024 · For example, if you know that 4 of the angles in a pentagon measure 80, 100, 120, and 140 degrees, add the numbers together to get a sum of 440. Then, subtract this sum from the total angle measure for a pentagon, which is 540 degrees: 540 – 440 = 100 degrees. So, the missing angle is 100 degrees. WebJul 12, 2024 · The ( x, y) coordinates for the point on a circle of radius 1 at an angle of 30 degrees are (√3 2, 1 2). By drawing a the triangle inside the unit circle with a 30 degree angle and reflecting it over the line y = x, we can find the cosine and sine for 60 degrees, or π 3, without any additional work.
