hypotenuse.
In a specific angle for a right triangle the cosine ratio is the ratio between the lengths of the adjacent side (side touching the angle) and the hypotenuse (longest side).
You need a bit more information to solve that one, because it's not clear whether the angle is opposite the leg you know or adjacent to it. If the angle is adjacent to the known leg, then divide the length of the leg by the cosine of the angle. If the angle is opposite the known leg, then divide its length by the sine of the angle.
Are two angle of a triangle that are not adjacent to the exterior angle
Opposite and adjacent sides.
Its Tangent, APEX "The tangent of an angle is the ratio of the opposite leg length to the adjacent leg length."
Fora right angle triangle: cosine angle = adjacent/hypotenuse
In a right angle triangle it is: cosine ratio = adjacent/hypotenuse
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
That's the cosine of the angle to which the 'adjacent' side is adjacent.
The adjacent side or base of the triangle.
adjacent side to the hypotenuse in a right triangle.
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine
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.
In a right angle triangle if the lengths of the adjacent or the hypotenuse are known.
If you mean cosine then it is angle ratio found in a right angle triangle which is adjacent/hypotenuse
To find the cosine of an angle, you divide the adjacent side of the triangle by the hypotenuse. A helpful hint for the trig functions of sin, cos, and tan is SOH CAH TOA. It's a helpful way to remember what to do. For Sine you divide the opposite side by the hypotenuse. In Tangent, you divide the opposite side by the adjacent side.
Adjacent Side / Hypotenuse = Natural Cosine of the Angle. For example: Adjacent Side=20cm / Hypotenuse=40cm = 0.5 Look up 0.5 in a Natural Cosine table and look back to the degrees on the left margin, you'll find 60... 60 degrees is the angle between the hypotenuse and the adjacent side.
