Question

Given that Cos of theta= -0.866, where frac{\pi }{2}" alt="\frac{\pi }{2}" align="absmiddle" class="latex-formula"> < theta < π, find Sin of Theta

Answer 1

Answer:

sin(theta) = 0.5

tan(theta) = -0.577

Step-by-step explanation:

Cos theta = -0.866

Theta = 2.617943073

(Because in the second quadrant)

sin(theta) = 0.5

tan(theta) = -0.577
