15)
ABCD is quadrilateral
∠MBC+∠ABC=180°
∠ABC =
The sum of all angles of quadrilateral = 360°
( Subtract 112 from both sides)
(Simplify)
(Divide both sides by 21)
___
16) Find m∠v
The polygon has 6 sides
Sum of angles:- (6-2)=180= 720°
so,
( Subtract 321 from both sides)
(Simplify)
( Divide both sides by 21)
Therefore, m∠v=19
____
Answer:
Option B
