Question 37742: Photobucket - Video and Image Hosting

in the diagram, two chords of Circle O, AC and BD intersect at E. measure of angle DEC=88 and measure of arc DC= 81. what is the measure of arc AB?

You can put this solution on YOUR website!
The inner intersection is the average of the two arcs it cuts off.
Thus if 88 = (1/2)(81 + arc AB)
176 = 81 + arc AB
arc AB = 95 degrees
