PQRS is a cyclic quadrilateral. If angle P is two times the angle R and angle S is four times the angle Q, then the sum of the angles Q and R is? |
96° 60° 36° 180° |
96° |
2x + x = 180° (Sum of opposite angles in cyclic quadrilateral is 180°) 3x = 180° x = 60° 5y = 180° y = 36° x + y = 60° + 36° = 96° |
