Answer:  The lengths of the segments of the other chord are 3 units and 8 units.

Step-by-step explanation:  As shown in the attached figure below, let the chords AB and CD intersect inside the circle at the point O, where

AO = 4 units,  OB = 6 units,   Co = 3 units.

We are to find the length of OD.

We have the following theorem :

<u><em>Intersecting Chord Theorem:</em></u>  When two chords intersect each other inside a circle, then the products of their segments are equal.

Applying the above theorem in the given circle, we must have

AO\times OB=CO\times OD\\\\\Rightarrow 4\times6=3\times OD\\\\\Rightarrow 24=3OD\\\\\Rightarrow OD=\dfrac{24}{3}\\\\\Rightarrow OD=8.

Thus, the lengths of the segments of the other chord are 3 units and 8 units.

Let (-5,-4) be a point on the terminal side of (theta). Find the exact values of cos, csc, and tan.
Rasek [7]

The exact values of the trigonometric identities cos, csc and tan as required in the task content are; -√41/5, -√41/4 and 4/5 respectively.

<h3>What are the exact values of cos, csc and tan as required in the task content?</h3>

It follows from above that the terminal side of the angle theta as described is on the point with coordinates (-5, -4).

Hence, the points spans 5 units leftwards and r units downwards on x and y axis respectively.

Hence, the length of the line that describes the angle by Pythagoras theorem is;

h = √((-4)² + (-5)²)

h = √41.

Hence, it follows from trigonometric identities that;

Cos (theta) = -5/√41.

Csc (theta) = -√41/4

Tan (theta) = 4/5
