Cosine of 65

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. There's really only one unknown. WebThe cos of 65 degrees equals the x-coordinate (0.4226) of the point of intersection (0.4226, 0.9063) of unit circle and r. Hence the value of cos 65° = x = 0.4226 (approx) Cos 65° in Terms of Trigonometric Functions Using trigonometry formulas, we can represent the …
