Question

In the given figure, OC and OD are bisectors of angle C and angle D, respectively. If angle A = 115°, find angle B​

Answer 1

Answer:

65 degree

Step-by-step explanation:

Angle A + Angle B = 180 degree ( adjacent angles)

115 + B = 180

B=180-115

B=65 degree

Answer 2

Answer:

Angle B is 85 degree because sum of all angles of quadrilateral is 360
