Where is the tangent secant angle on a circle?

The tangent secant angle is the angle between the tangent to a circle and the secant, when the latter is extended.


A tangent segment and a secant segment are drawn to a circle from a point outside the circle. The length of the tangent segment is 15 inches. The external segment of the secant segment measures 5 inches. What is the measure of the internal secant segment?

Answer · 0 votes Length of interior part of secant = 40 inches Please see attached image for diagram with work shown Image transcriptions The tangent—secant theorem states that if a tangent and a secant are drawn from the same external point, the length of the tangent squared is equal to the external part of the secant multiplied by the whole segment. 15_ Let x = the length of the inner segment of the secant II'I ' Length whole secant = length interior of secant + length exterior of secant 5 in = x + 5 (tangent? = (length exterior) * (length whole secant) (15)2 = (5) * (x + 5) 225 = 5x + 25 200: 5x 40:): Measure of internal segment = 40 inches More


A secant tangent passes through the center of a circle?

Neither secant nor tangent pass through the center of a circle. A secant passes through one point on the circle and the tangent passes through two points on a circle.


Does a secant tangent angle pass through the center of the circle?

Neither secant nor tangent pass through the center of a circle. A secant passes through one point on the circle and the tangent passes through two points on a circle.


Is a tangent always always a secant?

yes.


How do you solve secant squared divided by tangent?

In trig, the secant squared divided by the tangent equals the hypotenuse squared divided by the product of the opposite and adjacent sides of the triangle.Details: secant = hypotenuse/adjacent (H/A) and tangent = opposite/adjacent (A/O);Then secant2/tangent = (H2/A2)/(O/A) = H2/A2 x A/O = H2/AO.


Difference between secant lines and tangent lines?

A secant line touches a circle at two points. On the other hand a tangent line meets a circle at one point.


Can a line be tangent to one circle and a secant to the other in concentric circles?

Yes, it can as long as it is not the tangent line of the outermost circle. If it is tangent to any of the inner circles it will always cross the outer circles at two points--so it is their secant line--whereas the tangent of the outermost circle is secant to no circle because there are no more circles beyond that last one.


Which trigonometric functions have asymptotes?

tangent, cosecants, secant, cotangent.


What is the difference between a tangent and a secant?

They are different trigonometric ratios!


Is the vertex of a secant-tangent angle a point on the circle?
