    Finding Theta

    I'm trying to find an awser for theta.

    r= 6meters, s= 8meters, theta=?

    How do I find what theta would be?

    Also...is there a certain number that theta stand for?

    r is the rdius of a circle and s is the length of the arc subtended by the angle theta.

    This is trig, so I can bet that r and s are legs of a triangle. However, which legs are they? Also, which angle is theta? You need to paint a better picture for us to help you?

    And I thought it was a triangle...



    s=r \theta

    Theta is the angle in radians.

    This is all the information that I am given. I hagve to find what theta equals when I am given the radius and the length. Is there some type of formula to go by?

    Did you read my last post at all?

    s=r\theta

    \theta = \frac{s}{r}, where s is arc length and r is radius
