Question

find the value of sin 87 degree​

Answer 1

Answer:

Sin 87°= 0.998

Step-by-step explanation:

Since 87° is between 0° and 90°

87° is an acute angle since it is less than 90° and Sin 90° = 1, so it is obvious that value of Sin 87° is less than 1

Sin 87°= 0.998

Answer 2

hey mate:

find here:

. sin 83°=?

then, of all, you need to know some trigonometric formula:cosα=sin(90∘−α).Next, you need to know that for angles that are adequately small, the following relation holds:θ≈sinθ, θ→0.Notice that θ is expressed in radians. Therefore, we havecos87∘=sin3∘≈3∘=3π/180=π/60=0.05236

I hopes its helps u.
