sine
Sine = opposite / hypotenuse
sine
sin θ : 1 = the length of opposite side to angle θ : the length of the hypotenuse
22, The shortest side is opposite the smallest angle. As it is a right angle triangle, the Sine ratio can be used: Sine = opposite/hypotenuse ⇒ hypotenuse = opposite/sine = 11/sine 30o = 11 ÷ 1/2 = 22
If the angle opposite the side of 12.5 meters is 30 degrees then use the sine ratio to find the hypotenuse which works out as 25.0 meters.
Sine = opposite / hypotenuse
sin is short for sine. Sin(x) means the ratio of the side of a right triange opposite the angle 'x' divided by the length of the hypotenuse. cos is short for cosine. Cos(x) is equal to the similar ratio of the side adjacent to the angle 'x' divided by the length of the hypotenuse. tan is short for tangent. Tan(x) is equal to the ratio of the opposite side divided by the adjacent side. This is the same as sin(x)/cos(x).
It is the sine ratio.
Opposite over hypotenuse. Sin=opposite/hypotenuse cos=adjacent/hypotenuse tan=opposite/adjacent
Sin = Opposite/ Hypotenuse. If the angle is 90o then the Opposite IS the Hypotenuse so the ratio is 1.
Sine ratio = opp/hyp
its the cosine.. thanks to the dude up there i got it wrong and that was my answer for 4.1.3.
sine
Sine
in a right trianlge the tangent is the ratio of Opposite/Adjacentcosine is Adjacent/Hypotenusesine is Opposite/Hypotenuse
The side opposite the 30° angle is 1/2 the hypotenuse or 0.5 hThe side opposite the 60° angle is (sin60°) times the hypotenuse or about 0.866 h
Sine ratio = opposite/hypotenuse
