Solve the equation r1=r2 where 0 (degrees)<theta<360?

R1=2

R2=2-2sin(theta)

Separate with comas! Please help! How do I start this

    If I understand this correctly R1 which is 2 will be equal to R2 when it is 2. Sin(theta) is 0 at 0, 180, or 360 degrees. So, you would have 2 = 2-0 = 2. So theta is equal to 0, 180 or 360 degrees.

    2 = 2 - 2 sin(theta)

    0 = -2 sin(theta)...

    sin(theta) = 0 -> x = 180° is the only solution, as x = 0° and x = 360° were both excluded from your interval.

    R1=R2 -->sin(theta) = 0 ---> (theta) = ...
