Question

bo and co are the external bisectors of Angle B and angle C of a triangle ABC intersecting at o if angle A is equals to 60 degree angle abc is equal to 70 degree and find the angle BOC​

Answer 1

Answer:

Hi! Your answer is 120 degrees

Step-by-step explanation:

Let angle BOC be x.

We will first find angle ACB by angle sum property which will be equal to 50 degrees. (70+60+ angle ACB= 180)

Since OB and OC are angle bisectors

Therefore, angle OBC will be equal to 35 degrees and angle OCB will be equal to 25 degrees.

We will again use angle sum property in the triangle OBC.

25 + 35 + x= 180 degree
