Calculating the sides of a triangle helps you to determine the perimeter of a triangle even if you only have the measure of two of the angles and one of the sides. To find the sides of the triangle, you need to use the Law of Sines. A scientific calculator with trigonometric functions ...
. A scientific calculator with trigonometric functions will help you to find the sine of each of the angles. According to the Law of Sines, the ratio of the sines of each angle divided by the length of the opposite side are all equal. This helps you to find the sides of the triangle....
Therefore, to find the cotangent of an angle x, you need to first identify the adjacent and opposite sides of a right triangle that contains the angle x, and then take the ratio of these two sides. How do you find cotangent on a calculator? To find the cotangent of an angle with a ...
