Answer:

  P(x, y) = (√3/2, -1/2)

Step-by-step explanation:

There are a few special angles whose trig functions are worthwhile to remember. The top half of the table in the second attachment shows these.

The first attachment shows a unit circle and coordinates of the points at these special angles. It is worthwhile to remember there are 2π radians in a circle, so -π/6 radians (your angle) corresponds to a positive angle of 11π/6 radians.

__

The coordinates of P are ...

  P(x, y) = (√3/2, -1/2)

_____

<em>Additional comment</em>

The coordinates of any point at angle α on a unit circle are ...

  (x, y) = (cos(α), sin(α))

A triangle has angles measuring 15° and 45°. What is the measurement of the triangle’s third angle?
nexus9112 [7]
First you need to know that the internal angles of a triangle always equals 180°. Therefore:

15+45= 90°

Then since the angles should equal 180, you do:

180-90=90

So the missing angle equals 90°
