Cosine of 65

WebSine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the triangle is To calculate them: Divide the length of one side by another side Example: What is the sine of 35°?

WebCosine calculator Arccos definition The arccosine function is the inverse function of cos (x). arccos ( x) = cos -1 ( x) For example, If the cosine of 60° is 0.5: cos (60°) = 0.5 Then the arccos of 0.5 is 60°: arccos (0.5) = cos -1 (0.5) = 60° Arccos table See also Cosine calculator Sine calculator Tangent calculator Arcsin calculator WebSo the law of cosines tells us that 20-squared is equal to A-squared, so that's 50 squared, plus B-squared, plus 60 squared, minus two times A B. So minus two times 50, times 60, times 60, times the cosine of theta. This works out well for us because they've given us everything.
