Question

In a AABC, if ZA = 60°, ZB=80° and the bisector of ZB and ZC meet at O, then find ZBOC.​

Answer 1

Answer:

It is easy follow my steps

make a triangle roughly, then name the angle at left be angle c and angle at right be angle b also angle at top be angle a Now draw two line from b/w angle b and c so they meet at a common point o ans:

Given: angle a=60°

angle b=80°

To find: angle c and angle BOC Solution: angle a+b+c=180°[angle sum

property of triangle] 60+80+c=180

c=180-140

c=40

therefore angle c =40

Answer 2

Answer:

angle BOC = 120°

Step-by-step explanation:

Direct concept:-

Z BOC = 90° + 1/2 ZA
