Question

x tan 450 cos 600 = sin 600 cos 600 , then x = (a) 1 (b) 1/2 (c)1/ √2 (d) √2 (e) √3

Answer 1

Answer:

Answers: sin(π/4) = √2/2 or 1/√2; cos(π/6) = √3/2; tan(π/3) = √3 ... radians. sin A = 0; cos B = √3/2; sin C = 1/2; sin D = 1; tan E = 1; ... Then the Law of Sines gets you the other two sides:.
