In the figure below (not drawn to scale). A,B and C are there points on a circle with centre O. The chord BA is extended to a point T such that CT becomes a tangent to the circle at point C. if angle ATC = 30° and ACT = 50°, then the angle BOA is
Correct Answer : A
In the given figure BC = AC, angle AFD = 40° and CE = CD. The
value of angle BCE = ?
Each side of a given polygon is parallel to either the X or the Y axis. A corner of such a polygon is said to be convex if the internal angle is 90o or concave if the internal angle is 270o. If the number of convex corners in such a polygon is 25, the number of concave corners must be
Three runners A, B and C run a race, with runner A finishing 12 meters ahead of runner B and 18 meters ahead of runner C, while runner B finishes 8 meters ahead of runner C. Each runner travels the entire distance at a constant speed. What was the length of the race?
