Question

in fig. 13.111,PQRS is an isosceles trapezium.find x and y
From R D sharma class 9th ch - quadrilaterals
VSAQs​

Answer 1

Answer:

3x + 2x =180

x=180/5=36

in isochores trapezium the adjacent angle of the greater parelel side are Equal so

2x = y

y=36*2=72

Answer 2

Step-by-step explanation:

trapezium ,one side is parallel

SR||PQ

3x+2x=180°[allied angles make supplementary]

5x=180°

x=180/5

x=36

y=?

IN ISOSCELES TRAPEZIUM BASE ANGLES ARE EQUAL

2X=Y

2×36=Y [x=36]

72°=y

x=36. y=72°
