Explanation:
Angle ABC = Angle ABD + Angle DBC
Since triangle BCD is equilateral, all of it's angles must be
Since triangle ABD is isosceles, angle BAD is the same as angle BDA (
To find angle ABD, we have to use the Triangle Angle Sum Theorem that tells us the interior angles of a triangle add up to
So:
Thus angle
