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
Sin is sin-1(opposite/hypotonose)
If you have a right triangle, the sine of an angle is the ratio of the opposite side to the hypotenuse.
use right triangle trig... sin (angle) = opposite side/hypotunese, cos (angle) = adjacent side/hypotunese, and tan (angle) = opposite side/ adjacent side
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!Yes. That is why it is called a 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.
It means the ratio of the opposite angle to the hypotenuse of a triangle for angle "x". This is for a right triangle.
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.
Sin is sin-1(opposite/hypotonose)
The dimensions given fits that of a right angle triangle and sin^-1(12/13) = 67.38 degrees
If you have a right triangle, the sine of an angle is the ratio of the opposite side to the hypotenuse.
sin of angle a = opposite/hypotenuse = 1/3 sin-1(1/3) = 19.47122063 degrees
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.
use right triangle trig... sin (angle) = opposite side/hypotunese, cos (angle) = adjacent side/hypotunese, and tan (angle) = opposite side/ adjacent side

when you have a right triangle and one of the two non-right angles is theta, sin(theta) is the side of the triangle opposite theta (the side not touching theta) divided by the side that does not touch the right angle
