B) 40°
C) 80°

Answer 1

Answe is 100

Explanation:

Answer 2

Option D.)
`100 \textdegree` is correct.

Explanation:

In a quadrilateral, ABCD, opposite angles are supplementary.

`\angle BCD + \angle BAD = 180\textdegree`

therefore
`\angle BCD = 180\textdegree - \angle BAD = 180\textdegree - 80\textdegree = 100 \textdegree`

therefore option D.)
`100 \textdegree` is correct.
