Question

in a quadrilateral, /A=/B=78°and /D=107°,find /C​

Answer 1

Answer:

C = 97°

Step-by-step explanation:

According to the angle sum property of a quadrilateral, sum of all the angles of a quadrilateral = 360°

so, A + B + C + D = 360°

=> C = 360 - A - B - D

=> C = 360 - 78 - 78 - 107 = 97°
