Answer» The angles in a quadrilateral SUM up to 360°.The angles given here in the ratio form are : 4x, 5X, 10X and 11X.Hence, 4x + 5x + 10x + 11x = 360⇒ 30x = 360⇒ x = 360/30⇒ x = 12Hence, the angles = ? ⇒ 4x = 4(12) = 48°⇒ 5x = 5(12) = 60°⇒ 10x = 10(12) = 120°⇒ 11x = 11(12) = 132°Therefore, the angles are : 48°, 60°, 120° and 132°.__________________Important :A quadrilateral is a four SIDED shaped.It has 4 vertices.Sum of interior angles : 360°Perimeter is the sum of all four sides.Area = ½×diagonal×(sum of perpendicular heights)____________________ |
