Answer 1

Answer:

very easy u should have studies the circles theorem that angels is the same segment are equal and are half if the angle at the centre in opposite segment

now we are give angle BAD =75 using theorem

75×2 = 150 so angle BOD = 150

Step-by-step explanation:

Now given that BC = CD eqn@

so, BOC=COD=75 from eqn @

Now , triangle Now in triangle OBD

OB=OD radius so angle OBD=ODB eqn●

NOW angle sum property of triangle

OBD + ODB + BOD = 180

NOW from eqn ●

2OBD = 180-150

OBD=30/2

OBD= 15 ANS..

NOW ABCD IS cyclic quadrilateral so

sum of opposite side = 180

now BAD + BCD = 180

BCD = 180-75

BCD = 105..
