","description":"You probably know many of the trigonometry functions for the more common angles. A simpler example would be 0.5 degrees is equivalent to 0.5 * 60 = 30 minutes, so half of one degree, which makes sense. Multiply the 45) Find the length of the arc of a circle of diameter 12 meters subtended by the central angle is 63circ. Can they be computed by hand? Whichever method you use, just be sure to carefully follow any directions and have a working knowledge of the relationships between the different functions. You need only two given values in the case of: one side and one angle two sides area and one side Remember that if you know two angles, it's not enough to find the sides of the triangle. Each degree is divided into 60 minutes, and each minute further divided into 60 seconds. There are 60 seconds in 1 minute.).

When using the calculator to evaluate inverse trig functions, you really need to know about the domain and range of the function to get an accurate reading. WebClearly we have 15 degrees, so the remaining 0.6358 is minutes and seconds. So the decimal form (0.45) you have above needs be converted into minutes and seconds (the 172 degrees will stay the same.) The question asks to the nearest minute, it also asks express 172.45 as an angle. 16.12 (/11) 4.6 ft.

One degree is equal to 60 minutes and one minute is equal to 60 seconds. So, to express an angle measuring You can find tables that give function values to the nearest degree and the nearest minute.
