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
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
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 would you find out the sin tan and cos of right angle triangle?
sin, tan and cos can be defined as functions of an angle. But they are not functions of a triangle - whether it is a right angled triangle or not.
What does sin x mean?
It means the ratio of the opposite angle to the hypotenuse of a triangle for angle "x". This is for a right triangle.
What is sin y?
The Sine function (abbreviated sin) takes an angle and gives a ratio which is based on the sides of a right triangle. If you have a right triangle, and one of the angles (not the right angle) is labeled y then sin y equals the length of the side opposite of angle y divided by the length of the hypotenuse. The hypotenuse of a right triangle is the longest side, and is always opposite of the right angle.
How do you find the sine of an angle in a right triangle?
Sin is sin-1(opposite/hypotonose)
What is the sin of angle A 5 13 12?
The dimensions given fits that of a right angle triangle and sin^-1(12/13) = 67.38 degrees
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.
If the side opposite angle A of a right triangle is 30 meters and the hypotenuse is 90 meters what is the sin of angle a?
sin of angle a = opposite/hypotenuse = 1/3 sin-1(1/3) = 19.47122063 degrees
How do you find sin of angle?
The sine of an angle is obtained from a right angle triangle. The other two angles are acute, or less than 90 degrees. The sin of the angle is the side opposite the angle divided by the hypotenuse.
When one angle in a triangle is right angle it is called as?
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
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!
A triangle with one right angle?
A triangle with 1 right angle is a right angle triangle.
