Question

In a triqngle ABC if AB =AC and A=70° find triangle B triangle C​

Answer 1

Step-by-step explanation:

since AB=AC therefore angle opposite to these sides are equal

i.e. angles B and C are equal

now sum of the angles if the triangle is 180

A+B+C=180

70+B+C= 180

B+C=110

from above as B and C are equal

2B=110

B=C=55
