Question

solve this question please

Answer 1

it is equal to 120 .the explanation of it is given before
angle pqr + angle qps is equal to 180 degree
and
also angle qpd + angle pdq + angle p q d is equal to 180 degree
since angle qpd is half of angle pqr so
half of angle pqr + angle qps + angle qps is equal to 180 degree
half of angle pqr + 2 angle qps is equal to 180 degree
so on solving this to equation we get angle pqr is equal to 120 degree and Angle qps is equal to 60 degree
