Answer:
<1=83
<2=97
<3= 83 (given)
<4=97
<5=83
<6=97
<7=83
<8=97
Step-by-step explanation:
They give you the angle for 3 which is 83, so from there all you have to do is find the equivalent angles which are angle 1,5,7. Then for angles 2,4,6,8 you subtract 83 from 180 and you get 97.
Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.

Answer:
D
Step-by-step explanation:
You distribute the 2 to both numbers to get 2x-2=11, move the 2 to the other side by adding it to the 11. 2x=13. Divide 13 by 2, and X=6.5
