the angles in a circle = 360 angles in a quadrilateral = 360 angles in a triangle = 180 angles on a straight line = 180

I really think this is the picture for the first question only because I just helped you. use the formula I gave yes plug the numbers to find the length of the arc CD is l; and the angle theta is 45

What is the arc length of arc CD in the circle below? Circle A is shown with a radius labeled 15 feet and a central angle marked 45 degrees. 3.14 feet 4.88 feet 6.98 feet 11.78 feet thats the one that goes with thee picture, i confused the 2

Which equation could be used to solve for the measure of angle Q? Circle N is shown with a quadrilateral OPQR inscribed inside it. Angle O is labeled x degrees. Angle P is labeled y degrees. Angle Q is labeled z degrees. Angle R is labeled w degrees. z − (w + x) = 360 z + w + x = 360 z + x = 180 z + w = 180
