What is the arc tangent of pi over two?
The arc tangent is the recicple of the tangent which is also known as the cotangent. The tangent of π/2 is undefined, thus the cotangent would be zero.
What is the measure of the angle formed by two tangents drawn to a circle from an external point if they intersect a major arc whose measure is 230?
-- The major arc = 230 degrees-- The minor arc ... the arc between the tangents ... is (360 - 230) = 130 degrees.-- The line from the vertex of the angle to the center of the circle bisects the arc,so the angle between that line and the radius to each tangent is 65 degrees.-- The radius to each tangent is perpendicular to the tangent. So the radius, the tangent,and the line from the vertex to the center of the circle is a right triangle.-- In the right triangle, there's 90 degrees where the radius meets the tangent, and65 degrees at the center of the circle. That leaves 25 degrees for the angle at thevertex.-- With another 25 degrees for the right triangle formed by the other tangent,the total angle formed by the two tangents is 50 degrees.
How many lines of symmetry does a semicircle have?
One. The line of symmetry for a 180 degree arc (a semicircle) is the line that bisects the arc.
What is the function which outputs an angle when a tangent value is input?
The inverse tangent, also called the arc-tangent.
If the measure of a tangent-chord angle is 74 then what is the measure of the intercepted arc inside the angle?

How many ways can an arc be tangent to 2 lines?
Although normally it is the line that is considered to be tangent to an arc, an arc can be tangent to infinitely many lines and so the answer to the question is: in infinitely many ways.
How many ways can an arc be tangent to two line?

A line touching an arc or circle at only one point perpendicular to the arc's radius is said to be?
tangent
What is arc tg?
It is probably arctan or arc tangent, the inverse of the tangent function.
A line touching an arc or circle at only one point perpendicular to the arcs?
tangent

Line HA is tangent to the circle If arc AB is 90 degrees and arc AG 20 degrees. What is the measure of angle 1?
35 degrees :)
What does the tangent of an arc tangent of Y give or is equal to?
It is Y.
Is it true or false that the measure of a tangent-chord angle is twice the measure of the intercepted arc inside the angle?
It is true that the measure of a tangent-chord angle is half the measure of the intercepted arc inside the angle. When a tangent line intersects a chord of a circle, it creates an angle between the tangent line and the chord, known as the tangent-chord angle. If we draw a segment from the center of the circle to the midpoint of the chord, it will bisect the chord, and the tangent-chord angle will be formed by two smaller angles, one at each end of this segment. Now, the intercepted arc inside the tangent-chord angle is the arc that lies between the endpoints of the chord and is inside the angle. The measure of this arc is half the measure of the central angle that subtends the same arc, which is equal to the measure of the angle formed by the two smaller angles at the ends of the segment that bisects the chord. Therefore, we can conclude that the measure of a tangent-chord angle is half the measure of the intercepted arc inside the angle.

What is the term for a line that meets a circle or arc at only one point on it's exterior so it will not go through the circle?
a tangent to the circle
Line ha is tangent to the circle if angle 1 is 30 and arc ab is 90 what is the measure of arc ag?
The answer will depend on where the points a, b and g are as well as where angle 1 is. Since there is no information provided for these, it is not possible to answer the question
