Question

If sin theta is equal to 1/2 then find the value of cos theta

Answer 1

Answer:

root 3/2 (root over 3 only)

Step-by-step explanation:

we know,

sin^2 theta + cos^2 theta = 1

(1/2)^2 + cos^2 theta = 1

1/4 + cos^2 theta = 1

cos^2 theta = 1 - 1/4

cos^2 theta = 3/4

cos theta = root 3/2
