Question

what is the value of sin75​

Answer 1

Step-by-step explanation:

Sin(A+B) = Sin A Cos B + Cos A Sin B. Sin 75 = Sin ( 45 + 30) = Sin 45 Cos 30 + Cos 45 Sin 30. Sin 75 = (1 / √2) ( √3 / 2) + (1 / √2) ( 1 / 2) = [ √3 + 1] / 2√2.

Answer 2

Yo

Daddy here

sin75=sin(45+30)

You should be knowing that

sin(A+B)=sinAcosB+cosAsinB

Now just plug in the values to get the final answer.
