its the cosine.. thanks to the dude up there i got it wrong and that was my answer for 4.1.3.
What else can I help you with?
Is it true the sine ratio relates the length of the leg the angle that is in question to the length of the hypotenuse?
Yes... opposite an angle of a right triangle to the length of the triangle's hypotenuse.
What angle is the ratio of the opposite leg length to the adjacent leg length?
Its Tangent, APEX "The tangent of an angle is the ratio of the opposite leg length to the adjacent leg length."
How do you find the hypotenuse if you know one leg and one angle?
Remember the Trig. Functions. Sin(Angle) = opposite / hypotenuse. Hence algebraically rearranging. hypotenuse = opposite / [Sin(angle)) NB You MUST know the length of the 'opposite', and the size of the angle. So if the opposite is of length '2' and the angle is 30 degrees. Then substituting ;= hypotenuse = 2 / Sin(30) From Tables or calculator 'Sin(30) = 1/2 = 0.5' Hence hypotenuse = 2 / (1/2) or 2/(0.5) 2/(1/2) = 4 or 2/0.5 = 4 Hence the hypotenuse is '4' units in length.
In a 45-45-90 right triangle what is the ratio of the length of one leg to the length of the other leg?
1:1 since the two legs are the same size. The ratio between either leg and the hypotenuse is 1:(square root of 2)
What could be the ratio of the length of the longer leg of a 30-60-90 triangle to the length of its hypotenuse?
2 Square Root 3 And 4
Is a ratio of the length of the opposite leg to the length of the hypotenuse?
Sine
What is the ratio of the length of the opposite leg to the length of the hypotenuse?
sine
The ratio relates the length of the leg opposite the angle in question to the length of the hypotenuse?
sine
The sine ratio relates the length of the leg opposite the angle in question to the length of the?
hypotenuse.
What ratio relates the length of the leg opposite the angle in question to the length of the hypotenuse?
The sine.
Is it true the sine ratio relates the length of the leg the angle that is in question to the length of the hypotenuse?
Yes... opposite an angle of a right triangle to the length of the triangle's hypotenuse.
How do I find the length of the hypotenuse with one leg equalling 12 and the opposite angle being 30 degrees?
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.
What is the ratio of the short leg to the hypotenuse in a right triangle 30 60 90?
In a 30-60-90 triangle, the ratio of the lengths of the sides is 1:√3:2. The short leg, which is opposite the 30-degree angle, is half the length of the hypotenuse. Therefore, the ratio of the short leg to the hypotenuse is 1:2.
Fill in the blank The sine ratio relates the length of the leg opposite the angle in question to the length of the?
Hypotenuse, honey. It's like the diva of right triangles, showing off that ratio with style. So, if you wanna find out how long that leg is compared to the hypotenuse, just call up the sine ratio and let it do its thing.
Fill in the blank The ratio relates the length of the leg opposite the angle in question to the length of the hypotenuse?
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.
What could be the ratio of the length of of the longer leg of a 30 60 90 triangle to the length of its hypotenuse?
In a 30° 60° 90° triangle, the ratio (long leg)/hypotenuse = sqrt(3)/2 ~ 0.866The ratio (short leg)/hypotenuse = 1/2 = 0.5
What angle is the ratio of the opposite leg length to the adjacent leg length?
Its Tangent, APEX "The tangent of an angle is the ratio of the opposite leg length to the adjacent leg length."
