Best ResponseYou've already chosen the best response.1this 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!!

Best ResponseYou've already chosen the best response.1half 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!!

Best ResponseYou've already chosen the best response.1yep.. 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!
