Question

this is from chapter understanding quadrilaterals ....answer as soon as possible ​

Answer 1

$\huge{ANSWER}$

PORS is a trapezium (given)

PQ ll SR (given)

P= 30° (given)

Q= 50° (given)

Now,

P+S = 180°

[ Supplementary angles ]

(Property of trapezium)

S+ 30° = 180°

S= 180° - 30°

$\huge\boxed{S= 150°}$

Now, again

Q+R= 108°

[ Supplementary angles ]

R+ 50° = 180°

R= 180° - 50°

$\huge\boxed{R= 130°}$
