    theta = 9/19 radians or approximately. 4737 radians

    Step-by-step explanation:

    The formula for arc length is

    S = r theta

    where theta is in radians. Lets put in what we know. The radius would be 1.9 since the ropes would be the radius.

    .9 = 1.9 theta

    Divide by 1.9 on each side.

    .9/1.9 = theta

    theta = 9/19 radians

    or in decimal form it is approximately. 4737 radians
