Question

1. The angles P, Q, R and S of PORS are in the ratio 1:3:7:9. Find the measure
of each angle
​

Answer 1

Explanation:

trapezium with PQ || RS We know that, sum of all interior angle of quadrilaterals is equal to 360o. Let us assume the angles be x, 3x, 7x, and 9x Then, x + 3x + 7x + 9x = 360o 20x = 360o x = 360/20 x = 18 Therefore the angles are P= x = 18o Q = 3x = 3 × 18 = 54o R = 7x = 7 × 18 = 126o S = 9x = 9 × 18 = 162
