# Right triangle ratios?

They are called Pythagorean triples such as 2, 4 and 5

### What is the trignometric ratios?

There are six trigonometric ratios. Although applicable for any angle, they are usually introduced in the context of a right angled triangle. The full names of the main three ratios are sine, cosine, tangent. The other three ratios are reciprocals, which are cosecant, secant and cotangent, respectively. Suppose ABC is a triangle which is right angled at B. Thus AC is the hypotenuse. sin(A) = BC/AC = cos(C) cos(A) = AB/AC = sin(C) tan(A) =…

### Can a scalene triangle be a right triangle?

A scalene triangle is simply one which has no two sides equal to each other, or no two angles that are equal to each other. It's very possible that a right triangle could be a scalene triangle (or vice versa). For example, a 30-60-90 special triangle has sides that are related by the ratios 1, sqrt(3) and 2. This is clearly a scalene triangle. Not all right triangles are scalene, a 45-45-90 right triangle is…

### What are the trignometric ratios?

There are three trigonometrical ratios for finding the angles and lengths of a right angled triangle and they are tangent, cosine and sine usually abbreviated to tan, cos and sin respectively. tan = opp/adj cos = adj/hyp sin = opp/hyp Note that: opp, adj and hyp are abbreviations for opposite, adjacent and hypotenuse sides of a right angled triangle respectively.

### What is one of the trigonmetric functions?

The three basic trigonometric ratios are sine (sin), cosine (cos) and tangent (tan) They are found by comparing two of the three sides of a right triangle. The hypotenuse is the the longest side of the right triangle, and is opposite the right angle. The other two sides are the legs. One leg is adjacent to an angle, and the other is opposite the angle. The three ratios are sin(x) = opposite/hypotenuse cos(x) = adjacent/hypotenuse…

### If a triangle has one side nine and one side fifteen what is the other side?

If you're talking about length there's no way of knowing w/o knowing the angles. I expect given the lengths that you are referring to a Right Triangle and the ratio you are looking for is the standard 3, 4 and 5 triangle. The 5 represents the hypotenuse and the 3 and 4 are the ratios of the sides of the right angle. Hence in your example the answer would be 12.
