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?
Answer & explanation
Correct answer: option 1
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°
