Each of 5 friends has x action figures in
asambeis [7]

Answer:

13

Step-by-step explanation:

<em>Here, each of the 5 friends has an x action figure. When they buy 11 more we have 5(x+11). Now they have a total of 120 action collections and here we have 5(x+11)=120</em>

→5(x+11)=120\\\\

→5x+55=120\\

→5x=120-55

→5x=65

→x=65/5\\

→x=13

<em>Hence, each of the friends has 13 action collections originally.</em>

Angle 1 and Angle 8 are Alternate Exterior Angles. Therefore, by the Alternate Exterior Angle Theorem, the measure of angle 8 is also 59 degrees. Hope this helped!
