The sine of an acute angle in a right triangle is equal to the ratio (length of opposite side)/(length of hypotenuse). The hypotenuse of a right triangle is the longest side, and is opposite of the right angle.
This may help you remember it:
Sin Cos Tan
O H A H O A. O means Opposite. A means Adjacent, and H means Hypotenuse.
Oh Heck Another Hour Of Algebra.
So Sin(Θ) = O/H ; Cos(Θ) = A/H ; and Tan(Θ) = O/A

How do you find the sine of an angle in a right triangle?
Sin is sin-1(opposite/hypotonose)
What is sin in trigonometry?
If you have a right triangle, the sine of an angle is the ratio of the opposite side to the hypotenuse.
When one angle in a triangle is right angle it is called as?
A right angle triangle
Does a right angle triangle have 90 degree angle?
Yes. That is why it is called a right angle triangle!Yes. That is why it is called a right angle triangle!Yes. That is why it is called a right angle triangle!Yes. That is why it is called a right angle triangle!
How do you find the other side of a right triangle?
use right triangle trig... sin (angle) = opposite side/hypotunese, cos (angle) = adjacent side/hypotunese, and tan (angle) = opposite side/ adjacent side
