Question

in following triangle ab=ac and angle b=70° find angle a​

Answer 1

Answer:

the triangle is not visible as you have not uploaded the picture

Step-by-step explanation:

Answer 2

Here, I triangle Angle b = 70°

and ab = ac so, angle a and c angles are equal

From angle sum property, sum of all sides of a triangle = 180°

So, angle A + angle C + 70° = 180°

A+C = 180°-70°

A+C = 110°

Here, angle A is equal to angle C

So, angle A = 110/2

= 55°

Therefore, angle A is equal to 55°
