Question

Using the graph below, find values for the radius r, the angle theta (in both degrees and radians), and the coordinates for the point P labeled. (Note: The angle theta is labeled Q on the graph.) what are the points for P

Answer 1

if we take the centre of the circle as being the origin, we can say that
 
x coordinate is :cos o = x/r so x
                                   = r cos o

and

y coordinate : cos(90-teta)= y/r
so y=r*cos(90-teta)

if teta is 29 degrees
y=r*cos(61)
and
x = r * cos(29)
