Question

in triangle abc <a = 110° and ab = ac find <b and <c​

Answer 1

Answer:

35°

Step-by-step explanation:

<c = <b (ab=bc)

Now, <a+<b+<c = 180°

110° + <b + <b = 180° (<c = <b)

110°+2<b = 180°

<b = 35°

<c = 35°

Answer 2

Answer:

<b and <c =35

explanation

due to angle sum property

<a +<b+ <c=180

as AB=AC

<B=<C

hence

<A+<B+<C= 180

<A+<B+<B= 180

<A+2<B= 180

110+2<B= 180

2<B= 180-110

2<B= 70

<B= 70/2

<B= 35

<C= 35
