Answer:
158.4 degrees.
Step-by-step explanation:
A line is 180 degress in total so subtract 21.6 from 180. Then you get 158.4
2x+x=36
Kim's Sister age
2x+x=36 Add "x and 2x"
3x=36 Divide both sides by 3
÷3 ÷3
x=12
Kim's sister is 12 years old

Multiply that by two to get Kim's age
12•2=24 Kim is 24 years old.
