Web19 okt. 2024 · If x is an acute angle and tan x = 3/4 Evaluate : cos x - sin x cos x + sin x asked by Opeyemi October 19, 2024 3 answers tanx = 3/4 draw the triangle, and you can see that the hypotenuse is 5, so sinx = 3/5 cosx = 4/5 Now just use those values in your expression. oobleck October 19, 2024 Word~bard answered by Opeyemi October 19, 2024 WebAfter completing one rotation, the value of the angle is 360° or 2π in radians. Thus, we can say, after reaching the same position, Cos 0° = cos 360° Or Cos 0° = 2π Therefore, the Cos 360° value = cos 2π = 1 Cos 360 Degrees Identities cos 360° = sin (90°+360°) = sin 450° cos 360° = sin (90°-360°) = sin -270° -cos 360° = cos (180°+360°) = cos 540° movies that daniel radcliffe acted in
