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))
Answer:
A. x-6
Step-by-step explanation:
The area of a square is given by the expression square inches. Now we need to find an expression that represents the length of one side of the square, in inches. To do that we need to factor
.
Since area of square is given by (side)^2
Hence one side of square is (x-6).
So choice A. x-6 is correct.
