Given that there is no "this" given in the question, it is impossible to say!
The tangent ratio for a right angle triangle is opposite/adjacent.
The ratio of the length of the side of a right angle triangle must be 3,4,5 16,56,65 are not in that ratio.
is called the cosine ratio
The tangent ratio.
In a right angle triangle it is: cosine ratio = adjacent/hypotenuse
cosine
Tangent
Sine ratio = opposite/hypotenuse
The sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.In terms of ratios, the sine of an angle is defined, in a right angled triangle, as the ratio of lengths of the opposite side to the hypotenuse.
It's Sine!
It's not possible to have a right angle triangle with sides of equal length. The sides on a right angle triangle are always in the ratio 3:4:5.
It means the ratio of the opposite angle to the hypotenuse of a triangle for angle "x". This is for a right triangle.
