Question

In triangle ABC if AB is equal to AC and BC is produced to D such that angle ACD is equal Hundred degree angle a is equal to –

Answer 1

Answer:20°

Step-by-step explanation: angle ACD is 100, since bc is extended to D, that means angle ACB is 180-100= 80.

Not since AB=AC, this means angle ABC = angle ACB = 80°.

So angle a = 180-b-c = 180-80-80=20°
