B- 29.68%
A is too little
C is too much off
D is way too much
So B is your answer
If a 4 sided figure has 360°...for each side we add, we add 180°.
you have a 7 sided figure (360° + 3(180°) = 900°)
adding up your angles (781) and subtract it from 900 =
x = 119°
I think this should be the answer!!
The answer is that y is equal to zero
