Answer 2

See the below solution

hope it helps

Step-by-step explanation:

In △ABC

∠BAC+∠ABC+∠ACB=180

(Angle sum property)

∠BAC+69 +31 =180

∠BAC=180 −100 =80

For segment BADCB,

VBDC and ∠BAC are angles in the same segment. So, they must be equal

∴ ∠BDC=∠BAC (Angles in the same segment are equal)

∠BDC=80
