These ncert solutions will help an individual to increase concentration and you can solve questions of supplementary books easily. 1. the angles of quadrilateral are in the ratio 3 : 5 : 9 : 13. find all the angles of the quadrilateral. let x be the common ratio between the angles. 2. Solution: let the common ratio between the angles be = x. we know that the sum of the interior angles of the quadrilateral = 360° now, 3x 5x 9x 13x = 360° ⇒ 30x = 360° ⇒ x = 12°. , angles of the quadrilateral are: 3x = 3×12° = 36° 5x = 5×12° = 60° 9x = 9×12° = 108° 13x = 13×12° = 156°. 2. if the diagonals of a parallelogram. This ncert solutions for class 9 maths contains answers of all questions asked in chapter 8 in textbook, mathematics. therefore you can refer it to solve quadrilaterals exercise questions and learn more about the topic. ncert solutions for class 9 maths chapter 8 quadrilaterals. class – class 9 subject – maths chapter – ch 8.
