Question

Pls answer tmw my exam​

Answer 1

Answer:

Angle ODC + Angle ADO = Angle ADC

35° + 35° = Angle ADC

70° = Angle ADC

Angle OCD + Angle BCO = Angle BCD

45° + 45° = Angle BCD

90° = Angle BCD

Angle ABC + Angle BCD + Angle ADC + Angle DAB = 360°

Angle B + 90° + 70° + 115° = 360°

Angle B = 360°–275°

Angle B = 85°
