Answer:

The clue to find 'x' is-

  • As both, the lines here are intersecting at a point to form VERTICALLY OPPOSITE ANGLES.

According to this theory (2x+20)=60

So, (2x+20)=60

=  2x=60-20

=  2x= 40

=  x=40/2

=  x=20 degrees

the answer is A. or 20.

that angle is equal to the 60 degree angle. that means that angle also equals 60 degrees. 2(20) is 40 and 40 + 20 is 60
