Answer» By the theorem from class 9we have,The ANGLE subtended by a chord at CENTRE is double the angle subtended at any remaining part of the circle.with this,angle Q = 2(30) = 60°and, angles in same segment are EQUAL so,angle R = 30°and angle C = 1/2(reflex of angle Q)angle C = 1/2(360 - 60)angle C = 1/2( 300)angle C = 150°Thanks.Like Follow and Rate.Teacher. |
