What are the coordinates of points p and q on the unit circle at right?

Part 1) Find the coordinates of point P

we know that
r=1 unit
x=r*cos 50°> x=1*cos 50°=0.64
y=r*sin 50°> y=1*sin 50°=0.77
the point P belong to the first quadrant
so x and are positive
the coordinates are (0.64,0.77)

the answer Part 1) is P (0.64,0.77)

Part 2) Find the coordinates of point Q
we know that
r=1 unit
angle=180-110=70°
x=r*cos 70°> x=1*cos 70°=0.34
y=r*sin 70°> y=1*sin 70°=0.94
the point P belong to the second quadrant
so
 x is negative> -0.34
y is postive> 0.94
the coordinates are (-0.34,0.94)

the answer Part 2) is Q (-0.34,0.94)
