Answer: the equal angles are 120 degrees each
Step-by-step explanation:
we know that all angles o quad. = 360degrees
take the angles as A , B , C , D
A+B+C+D=360
A=70 (Given)
B=50 (Given)
C=D
so now we have,
70+50+C+C=360
2C=360-120
2C=240
C=240/2
C=120
the equal angles are 120 degrees each

Answer:
120 degrees each
Step-by-step explanation:
Statement Reason
Two angles are 50 Given
and 70.
Let each equal angle be x.
Therefore,
x+x+50+70=360 Sum of angles in a quadrilateral equals to
2x+120=360 360.
2x=360-120
2x=240
x=240/2=120
Therefore equal angles are of 120.
