Notice also that sin θ = cos (π 2 − θ), sin θ = cos (π 2 − θ), which is opposite over hypotenuse. Given trigonometric ratio: sin 75 ∘. = 1/2 √2 . search. Knowing that sin (90 + θ) = cos θ, we can rewrite sin 105 degrees as sin (90 + 15) degrees. See Table 1. (since
Explanation: cos 105 = cos (15 + 90) = - sin 15. Step 6. Complete step by step answer:
