The trigonometric ratio that compares the opposite side length to the adjacent side length is what?
tangent
If you divide length of the opposite side of an angle in a right triangle by the length of the adjacent side what value do you get?
It is a tangent.
Does a trigonometry tangent relate to a circle's tangent?
A circle's tangent is exactly the same as a triangle's tangent. If you look at a circle, you can make the radius the hypotenuse. Then make a vertical line from the point, and a horizontal line from the center. If you look, you have a triangle made inside the circle. This is why angles can be measured in radians, a unit that is derived from the circumference of a circle.-------------------------------------------------------------------------------------------By doing a little calculus, we find that the slope of the equation of a circle-the slope of the tangent line-is given by the tangent of an angle.AnswerEverything written above is correct, but doesn't have anything to do with tangents (in the circle sense of the word). Suppose you're given an angle theta. Draw a circle together with two radii, one horizontal and the other at an angle theta from the first one. (So far, this is the same as above.) Now draw the tangent to the circle at X, the point where the non-horizontal radius meets the circumference. Let Y be the point where this tangent meets the horizontal line through the centre. Then, assuming the radius is 1, tan(theta) is the distance XY, which is the length of part of the tangent.
In maths what is Pi used for?
pi is used to work out things like the circumference (length around the outside) of a circle from the diameter (length from side to side (pi x d). It can also work out a circle's area (2pi x r(radius)), and much more with spheres and cylanders etc.
What is the length of the tangent line from the point 9 0 to a point where it touches the circle of x2 plus 8x plus y2 -9 equals 0?
Equation of circle: x^2 +8x +y^2 -9 = 0 Completing the square: (x+4)^2 +y^2 = 25 Radius of circle: 5 Center of circle: (-4, 0) Distance from (9, 0) to (-4, 0) is 13 which is the hypotenuse of a right angle triangle Using Pythagoras' theorem: 13^2 -5^2 = 144 and its square root is 12 Therefore length of tangent line is: 12 units Note that a tangent line always meets the radius of a circle at right angles.
What is the length of a tangent?
A tangent is a straight line and so has infinite length.
How is length of tangent formula calculated?
A tangent is a straight line and so is of infinite length. There is nothing in the question to suggest otherwise so the answer is simple: a tangent is of infinite length.A tangent is a straight line and so is of infinite length.

What is the length of the tangent?
A tangent is an infinitely long straight line.
What are spheres that have the same length radii called?
Congruent spheres
How do you calculate tangent of an angle?
the tangent of an angle is equal to the length of the opposite side from the angle divided by the length of the side adjacent to the angle.
What angle is the ratio of the opposite leg length to the adjacent leg length?
Its Tangent, APEX "The tangent of an angle is the ratio of the opposite leg length to the adjacent leg length."
What is the ratio of the length of the opposite leg to the length of the adjacent?
It is the tangent ratio.
What is length of tangent?
It is usually infinitely long.
If a circle of radius 2 is externally tangent to a circle of radius 8 what is the length of their common tangent?
the length of thr direct common tangent will be 2*{1/2 power of (r1*r2)} the answer will be 8 units in this case...
What is the tangent of a right triangle?
There is no such thing as the tangent of a triangle. Circles, angles, and conversations have tangents. In a right angled triangle, the tangent of one of the acute angles is the ratio of the length of the side opposite the angle to the length of the side adjacent to it.
The tangent ratio relates the length of the leg?
the opposite
The trigonometric ratio that compares the opposite side length to the adjacent side length is what?
