One degree is equal to 60 minutes and one minute is equal to 60 seconds. Note that the , and keys automatically open a bracket for you. Minutes and seconds are used to express fractions of degrees. Minutes and seconds are used to express fractions of degrees. One degree is equal to 60 minutes and one minute is equal to 60 seconds. So, to express an angle measuring Dummies has always stood for taking on complex concepts and making them easy to understand. We know the angle and the opposite side, so we can use the tangent to find the adjacent side, b. tan = Substitute the given values into the equation. {} . Try the given examples, or type in your own measure of angle S, to the nearest minute? Answer. Thats three values for three different angles in three different functions. Find the values of for the following (Give your answers in degrees and minutes): tan -1 2.53 = 68 25 59.69 ( The symbol denotes seconds. The minutes of an angle are the subdivisions of its degrees. So the decimal form (0.45) you have above needs be converted into minutes and seconds (the 172 degrees will stay the same.). (The funny part is, the online converters come up with the answer "26 minutes and 60 seconds," but since 60 seconds is another minute, I'm not sure why it would come up that way). How good are you at doing this? The next detail is to have the calculator set in the correct mode degrees or radians depending on what your application is and what form the angles that youre using are in. Some favorites are:
