in triangle BCO and B0E
CO = OE (radii of same circle)
bo = bo ( common)
BC = BE(given)
so by SSS congruence rule
triangle BCO is congruent to triangle BOE
BY CPCT
angle CBO = angle OBE ( eqn 1)
since abcd is a cyclic quad.
therefore angle D + angle B = 180
130 + angle B = 180
angle B = 50 degree
angle CBO + angle OBE = angle CBE
BUt angle cbo = angle OBE
therefore 50 + 50 = angle CBE
angle CBE = 100 degree
donot forget to make it brainlist answer.
