Question

In triangle ABC ik f AB=AC and angle B= 70 then angle A will be​

Answer 1

Answer:

We know that sum of angles of a triangle is 180°.

then if AB=AC, so angle B=angle C

Now angle A+angle B+angle C=180°.

2angleA=180°-70°

angle A= 110°/2

angle A= 55°

Answer 2

Answer:

angle A =70

Step-by-step explanation:

in triangle ABC

AB=AC

therefore triangle ABC is an isosceles triangle.

and angles opposite to equal sides in an isosceles triangle are equal.

Thus;

angle A = angle B=70.
