solve this question​

Answer 1

Answer:

We know that,

Triangle ABD and BDC are equilateral triangles.

Hence angle ABD is equal to 60 degrees.

Similarly DBC os also equal to 60 degrees

Hence, angle ABC =

$60 + 60$

equal to,

$120 \: degrees$

Hope this helps!

Answer 2

Answer:

Angle ABC is equal to 120°.

Step-by-step explanation:

We can see in the figure that ∆ABD and ∆BCD are equilateral triangle and we know that all angles of equilateral triangles are equal that is they are 60° each.

Now,

angle ABC = angle ABD + angle CBD

=> angle ABC = 60° + 60°

=> angle ABC = 120°
