Answer:

Step-by-step explanation:

2x+3+2x-12+4x-11=180 degree (sum of interior angles of a triangle)

8x-20=180

8x=180+20

x=200/8

x=25

Now , substitute the value of x.

Chicago=2x+3

=2*25+3

=50+3

=53 degree

Austin=2x-12

=2*25-12

=50-12

=38 degree

Atlanta=4x-11

=4*25-11

=100-11

=89 degree
