Identify the measure of arc RT◠ . The figure shows a circle and three secants. Points P, R, T, Y, W lie on the circle. Secants X S and X M intersect in the exterior of the circle at point X. Point Y lies on secant X S. The measure of angle W X Y is 45 degrees. The measure of arc W Y is 35 degrees. Secants X M and S P intersect in the interior of the circle at point M. The measure of angle X M S is 95 degrees. Secants S P and S X intersect in the exterior of the circle at point S. Point R lies on secant S P. Point T lies on secant S X. The measure of arc P W is 80 degrees. RT = 40° RT = 35° RT = 85° RT = 45°
