How do you find the angle of a cosine?
You mean, you have the cosine, and want the angle? That is called arc-cosine, often written as cos-1x. Your scientific calculator should have a "shift" key or something similar, which you press, followed by the cosine key. That will give you the inverse cosine or arc-cosine.
How do you find the hypotenuse with a cosine and or sine?
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine
Which angle length does cosine give you?
Sides have lenght, angles do not. Cosine is the ratio of the adjacent side to the hypotenuse. Cosine can be used to find either of these sides if the other is known.
What is the cosine function about?
The cosine function is mathematical equation to determine the adjacent angle of a triangle. The cosine of an angle is the ratio of the length of the hypotenuse: so called because it is the sine of the co-angle.
How is cosine defined?
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.

Where to use sine and cosine in physics?
The sine, cosine and tangent are used to find the degrees of a right angle triangle.
How do you find the hypotenuse with a cosine and or sine?
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine
What is the ratio of the cosine of an angle?
Fora right angle triangle: cosine angle = adjacent/hypotenuse
To find the cosine of an angle in a right triangle divide the adjacent by the?
hypotenuse.
How do you find the sec of a 38 degree angle?
Find the cosine of 38 degrees and then find its reciprocal.
Which angle length does cosine give you?
Sides have lenght, angles do not. Cosine is the ratio of the adjacent side to the hypotenuse. Cosine can be used to find either of these sides if the other is known.
What is the cosine of a 60 degree angle?
Cosine is 0.5
What is the cosine function about?
The cosine function is mathematical equation to determine the adjacent angle of a triangle. The cosine of an angle is the ratio of the length of the hypotenuse: so called because it is the sine of the co-angle.
How is cosine defined?
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
If the cosine of angle B is 0.2536 in a right triangle how can I find the measure of ( acute ) angle B with just that information?
Angle of B is cos^-1*(0.2536) = 75.309 degrees to three decimal places
How do you find the diagonal of a rectangle if you know the length and the angle?
You need to use trigonometry cosine (angle) = length/diagonal diagonal = length/cos(angle)
