First draw out the picture it will help. Then you can see that you want the opposite segment of the angle, which leads you to use a sine. So you have 20sin30 or 20(1/2) or 10ft.
A unit circle is the one which has radius equal to 1.
The relation between radius of circle (r), the arc length (s) and the radian measure of angle made by arc (Ф) is given as:
s = rФ
For a unit circle, r = 1, so the above equation becomes:
s= Ф
This means, the arc length will be equal to the angle made by that arc in radians.
If y>0 then y has to be 1 or more so
8= x+y
8= x + 1
-1
7= x
so x is < 8
