Question

If in Triangle abc,ab=ac angle a=100° then find Angleb and angle c

Answer 1

Answer:

b 100 & c 80gucgkcolhhchjgh

Answer 2

Answer:

angle a=100°

ab=ac

therefore,

angle b=angle c= x°(angles opposite to equal sides are equal)

In triangle ABC,

A+B+C=180 (angle sum property)

100+x+x=180

100+2x=180

2x=180-100

2x=80

x=80/2

x=40°

So,

angle b=angle c=40°
