Okay I don't need like a really confusing answer this is just for 8th grade physics and I don't understand why the 30 degree angle was better that the 40 degree angle since 40 is closer to 45 whih is the best angle I use the diamond rods on the sharpmaker and then strop a few times with a strop with diamond paste on it. Here is the work for this problem: 90 degrees (representing the right angle) + 50 degrees equals 140 degrees. When this is not the case, as in astronomy or for geographic coordinates (latitude and longitude), degree measurements may be written using decimal degrees, with the degree symbol behind the decimals; for example, 40.1875°. Home Problems and Answers Optics A light ray is incident on a glass plate at an angle of 40 degrees . so this video is very important for you. Figure 4: Acute angles — at 45° (Figure a), 60° (Figure b), and 30° (Figure c). All you have to do is follow these steps: Choose your initial angle - for example, 610°. radian measure = (degree measure × π)/180, 0.22222222222222π rad = 0.69813170079773 radian. $11.99 $ 11.
