Question

ABCD is a square. Diagonal DB and CP
intersect at O. angle BOP = 78°. Find x, y
and z. Urgently.​

Answer 1

Answer:

first prove the congruence between the given triangles and u will find a idea

Answer 2

DB is angle bisector of ADC then x=90/2=45°

DOC is vertical opposite of POB the doc is 78°then y= 33°

z=123° because APDC is a trapezium
