Question

The two angles of a quadrilateral are 50° and 70° and other two angles are equal. Find the equal angles. Plz write the steps. Who ever writes first in correct format will be marked as BRAINLIEST.

Answer 1

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 2

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.
