its the cosine.. thanks to the dude up there i got it wrong and that was my answer for 4.1.3.
If its a right angle triangle then the sine ratio is opposite/hypotenuse
Yes... opposite an angle of a right triangle to the length of the triangle's hypotenuse.
Its Tangent, APEX "The tangent of an angle is the ratio of the opposite leg length to the adjacent leg length."
1:1 since the two legs are the same size. The ratio between either leg and the hypotenuse is 1:(square root of 2)
2 Square Root 3 And 4
Use the sine ratio: sine 30 degrees = opposite/hypotenuse Then: opposite = 2*sine 30 degrees Answer: 1 foot
sine
Sine
hypotenuse.
sine
The sine.
Hypotenuse
Yes... opposite an angle of a right triangle to the length of the triangle's hypotenuse.
Rearrange the sine ratio of sine = opposite/hypotenuse: hypotenuse = opposite/sine hypotenuse = 12/sine 30 degrees = 24 Therefore the hypotenuse is 24 units in length.
Sin= Opposite leg/Hypotenuse Cos= Adjacent leg/ Hypotenuse Tan=Adjacent leg/ Opposite leg
This ratio is called the sine ratio for a right triangle. A simple way to remember this is by using the mnemonic 'SOHCAHTOA', where SOH stands for sine equals the ratio opposite side/ hypotenuse, COH is cosine equals adjacent side/hypotenuse, and TOA is tangent equals opposite side/adjacent side.
In a 30° 60° 90° triangle, the ratio (long leg)/hypotenuse = sqrt(3)/2 ~ 0.866The ratio (short leg)/hypotenuse = 1/2 = 0.5
