Answer:
your answer should be d
Step-by-step explanation:
X=60° (equilateral triangle)
y=120°
Working: (360°-120°)/2
She subtracted 6 from a certain number and then divided the result by 3, giving her 35.
(x - 6) / 3 = 35
x - 6 = 35*3
x - 6 = 105
x = 105 + 6
x = 111
so she should have subtracted 3, then divided by 6
(111 - 3) / 6 = 108/6 = 18 <===
