Answer:
100
Step-by-step explanation:
Angle a =75°,angle b=75° and angle d = 110°.
The sum of all angles of a quadrilateral =360°.
Therefore,angle c =
a+b+c+d=360
75+75+c+110=360
260+c=360
c=360-260 =100
Therefore angle c =100°

Answer:
THE ANSWER IS OPTION (B) 100
Step-by-step explanation:
SUM OF ANGLES IN QUADRILATERAL IS 360, THEN ∠A+∠B+∠C+∠D = 360
75+75+∠C+110=360
260+∠C=360
∠C=360-260
∠C=100
