Question

49. In the adjoining figure, ABC is an isosceles
triangle with AB = AC and ABC = 50°.
Then, BDC is equal to##solve step by step
​

Answer 1

Answer:

angle d =80°

Step-by-step explanation:

As it is an Isosceles triangle therefore angle B=angle ACB

therefore Angle A+50+50=180

Angle A=80

By theorem...ANGLES IN THE SAME SEGMENT OF A CIRCLE ARE EQUAL

therefore angle D is equal to angle A...

angle D=80°
