Knowing that sin (90 + θ) = cos θ, we can rewrite sin 105 degrees as sin (90 + 15) degrees. sin 105° + sin 15° = 2 cos 60° sin 45° O E. Click here:point_up_2:to get an answer to your question :writing_hand:how do you find the exact value of sin 105 degrees. Since we know that 15 is half of 30, we can plug 30∘ in as θ and simplify: sin(15∘) = sin(30∘ 2) = √ 1 − cos(30∘) 2.
