Answer:

A:59 B:48

Step-by-step explanation:

A triangle is equal to 180 degrees. So the equation would be

73+x+(x-11)=180. To find the value of x, add all of the same values

73-11+x+x which is equal to 62+2x=180. Then subtract 62 from both sides

62-62+2x=180-62  so the equation is now 2x=118 now you divide each side by 2 to get x=59. now to get angle b you subtract 11 from 59 to get 48
