Question

ABCD is a cyclic quadrilateral whose diogonal intersect at a point E . if angle DBC=70°, angle BAC is 30°, find angle BCD. Further , if AB= AC find angle ECD​

Answer 1

Answer:

80 cm

Step-by-step explanation:

DBC -70°

BAC -30°

70° +30° + x =180°

100° +x = 180°

x = 180° - 100°

x= 80°

ECD = 80°
