Answer: <em>15</em>
Step-by-step explanation:
<em>8x-60°</em>
<em>8(15)-60°</em>

X WILL EQUAL 15 BECAUSE 120 - 60 WILL EQUAL 60!
THE TRIANGLE MUST ADD UP TO 180°!!
Answer:
hence small rolls 60 and large rolls 70
Step-by-step explanation:
let club sold s small rolls
hence club sold s+10 large rolls
earning from small roll 3s
earning from large rolls 4.5(s+10)
hence
4.5(s+10) - 3s = 135
or 4.5(s+10) = 3s +135
3s +135 = 4.5(s+10)
3s +135 = 4.5s +45
4.5s +45 = 3s +135
4.5s -3s = 135-45
1.5s = 90
s = 90/1.5
s= 60
s+10 = 70
hence small rolls 60 and large rolls 70
