    this angle measure is universal.. alright,,i'll tell you,,but you have to reach the ans yourself..i'll drop hints when you require.. a tangent always makes a 90 degree angle with the radius!!

    Wait isn't the measure of the angle half the arc?

    half the arc? which arc?? you're confusing with another property of circle.. just remember this :a tangent always makes a 90 degree angle with the radius!!

    I don't get how you would find the angle measure

    see,,CAED is a quadilateral..you know 3 angles of it..cant you find the 4th?

    Would I subtract the three angles from 360?

    yep.. well 2 of those are 90 degress,,(radius tangent angle),,one is 126(given the ques) just find the 4th,,thats what the ques asks you to do!
