How do you determine which is the adjacent side of a right triangle?
There are three sides, hypotenuse, opposite and adjacent. But the adjacent and opposite are not fixed sides: it depends on which of the two acute angles you are examining.For either of the non-right angles, the adjacent side is the one which forms the angle, along with the hypotenuse. For the given angle θ, the length of the adjacent side compared to the hypotenuse (adjacent/hypotenuse) is the cosine (cos θ).
How do you find the unknown side of a right triangle given the length of another side and an angle?
opposite/hypotenuse = sin(x) adjacent/hypotenuse = cos(x) opposite/adjacent = tan(x) where 'x' is the angle in question.
Definition of the 6 trigonometric functions?
The six main trigonometric functions are sin(x)=opposite/hypotenuse cos(x)=adjacent/hypotenuse tan(x)=opposite/adjacent csc(x)=hypotenuse/opposite cot(x)=adjacent/opposite sec(x)=hypotenuse/adjacent Where hypotenuse, opposite, and adjacent correspond to the three sides of a right triangle and x corresponds to an angle in that right triangle.
How do you find the cos of a triangle?
Adjacent side / Hypotenuse
How do you find the sin of a triangle?
Sin is opposite over hypotenuse. Just think of this to help you: SOH-CAH-TOA Sine = opposite over hypotenuse Cosine = adjacent over hypotenuse Tangent = opposite over adjacent Hope that helps you.
How do you find the hypotenuse of a right triangle when only a side length and angle is given?
Dependent on what side you are given you would use Sin(Θ) = Opposite/Hypotenuse just rearrange the formula to Hypotenuse = Opposite/Sin(Θ). Or if you are given the adjacent side use Cosine(Θ)=Adjacent/Hypotenuse, then: Hypotenuse = Adjacent/Cosine(Θ)

How do you find an angle of a right triangle when 3 sides are given?
you need a calculator to do Sin-1 Opposite/hypotenuse OR Cos-1 Adjacent/Hypotenuse OR Tan-1 Opposite/Adjacent
What are facts about right triangles?
The ratio of the length of the side opposite a given angle to the hypotenuse is the sine of that angle.The ratio of the length of the side adjacent to a given angle to the hypotenuse is the cosine of that angle.The ratio of the length of the side opposite a given angle to the side adjacent to that angle is the tangent of that angle.
What is the leg next to a given angle in a right triangle?
If it isn't the hypotenuse, then it's the "Adjacent" side.
How To Use SohCahToa?
Sin= Opposite/Hypotenuse Cos= Adjacent/Hypotenuse Tan= Opposite/Adjacent
The cosine of an angle equals the ratio of the?
adjacent side to the hypotenuse in a right triangle.
The sine ratio of an angle is the opposite side over the adjacent side?
Opposite over hypotenuse. Sin=opposite/hypotenuse cos=adjacent/hypotenuse tan=opposite/adjacent
How do you find the unknown side of a right triangle given the length of another side and an angle?
opposite/hypotenuse = sin(x) adjacent/hypotenuse = cos(x) opposite/adjacent = tan(x) where 'x' is the angle in question.
What is the opposite side of an adjacent?
The opposite side of an adjacent is the hypotenuse. Sin(q) = Opposite / Hypotenuse Cos(q) = Adjacent / Hypotenuse Tan(q) = Opposite / Adjacent Reference: http://easycalculation.com/trigonometry/triangle-angles.php
Is the cosine adjacent to the hypotenuse?
Nearly! The cosine is the adjacent side (ie not the opposite side) divided by the hypotenuse.
What Is the value of cos?
Cos is the ratio between adjacent side (of the given angle thieta) to the hypotenuse of the triangle.
