Cosine of 8 degrees
WebMar 6, 2014 · I have a right triangle ABC with B = 90 degrees. AB is vertical, BC is flat and AC is the hypotenuse. The length value for AB = 125 and AC = 150. I want to find the value of angle A. I first try to find the cosine and then I want to convert the cosine to degrees. WebArccos Calculator. In mathematics, the inverse trigonometric functions are the inverse functions of the trigonometric functions. Specifically, the arccos is the inverse of the cosine. It is normally represented by arccos (θ) or cos -1 (θ). arccos = ?
