Question

The bisectors of ZB and ZC of a triangle
ABC meet at a point O. If ZA=60°, then
<BOC is :
(1)
30°
(2)
60°
(3)
90°
(4)
120°​

Answer 1

Answer:

The answer is (d) 120.

Step-by-step explanation:

It is because:

According to a property of triangle, if the two angles are bisected to form another triangle, then the new angle so formed will be equal to 90 = 1/2 A.

So by applying the property,

90+ 1/2(60)

90+30

=120
