Question

In the adjacent figure AB and AC are the tangents, AB = 6cm and A = 60 degree , then the perimeter of ABC is

Answer 1

Answer:

18 cm .

Step-by-step explanation:

Two same tangent drawn from A external point is same .

So , AB = AC = 6 cm.

Now as angle B = angle C = 60 degree ( Base angle of isosceles triangle = 60 degree ) .

So , ABC is equilateral .

So , perimeter of ∆ ABC = 6+6+6 = 18 cm .
