Answer 1

Answer:

Angle BOC = 115°

Step-by-step explanation:

There will be two triangle formed namely ABC and BOC. For triangle ABC the sum of angle is 180° one of them is 50°

The sum of remaining two angles will be = 180° - 50° = 130°

Now the sum of all angles of triangle will be 180°

two of these angles are halves of angles ABC and ACB so their their sum will be half of angle ABC and ACB =130°/2 = 65°

The third triangle BOC which is =180° - 65° = 115°
