Type the correct answer in the box. use numeral instead of words. if necessary, use / for the fraction bar.

For this question, all you have to do is solve the missing angle of the triangle ABD since it has two measurements already and the angle BCD is a reflection of the missing angle.

Since the total degrees of a triangle's angles should add up to 180°, let's add the given angles and then subtract that from 180.

83 + 34 = 117°

180 - 117 = 63°

So, the angle BCD is 63°.
Hope that helped!
