Answer 1

bro 30 - 180 _ 150 and then I don't know

Answer 2

Hey, here is your answer

given :- bd = dc and angle dbc = 30°
so , angle bcd = 30° (angle opposite to congruent side )
in triangle bdc
angle b +angle d+ angle c = 180°
30°+ angle d + 30° = 180°
angle d = 180° - 60°
angle d = 120°
angle bdc = 1/2 of mcarc bac
120°= 1/2 mcarc bac
120×2 = mcarc bac
mcarc bac = 240°
mcarc bac = 240°
mcarc bdc = 300°- mcarc bac
= 300° - 240°
= 120°
angle bac = 1/2 mcarc bdc (inscribed angle therom)
angle bac = 1/2 × 120°
angle bac = 60°
