Answer:
a) 115°
Step-by-step explanation:
first find the value of angles B and C by doing 180 - 50 =130 and then 130÷2 because B and C are equal
Since the lines BO and CO are bisectors, it means that the angles are halved fo take half of angle B plus half of angle C and add them together = 65 and then do 180-65=115 so the angle BOC is 115°
