I need help understanding how to solve this problem.

1. If on the unit circle C, the distance from P (1, 0) to the point T (5/13, 12/13 ) is x, determine the coordinates of the point at the indicated distance from P.

π+ x

Explanation:

It is indicated to find the coordinates of the point T (5/13, 12/13) at a distance π + x.

Then, the distance π+ x means that the point T is rotated 180º.

The rule for the rotation of a point 180º around the origin is:

Applying that rule to the point T:

D.

Step-by-step explanation:

From the given information we have :

and

Now we need to find :

We make use of trigonometric identities.

This implies that:

The correct choice is:

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
