Question

in figure a b c and d are concyclic points angle dbc =30,angle DCB=70 find angle BAC please help me

Answer 1

hlo

your answer..

in ΔBDC
angle DBC + angle BCD + angle BDC = 180
30 + 70 + angle BDC = 180
100 + angle BDC = 180

angle BDC = 180 - 100 = 80°


angle BDC = angle BAC ( angle in same segment)

angle BAC = 80°✔✔
