Step-by-step explanation:
(a)
There are 360° around a point, thus
food = 360° - (120 + 86 + 72)° = 360° - 278° = 82°
(b)
Form a fraction of clothing to whole circle and multiply by 100%, that is
clothing = [tex]\frac{72}{360}[/tex] × 100% = [tex]\frac{72(100)}{360}[/tex] = 20%
(c)
Form a fraction of entertainment to whole circle and multiply by $540
entertainment = [tex]\frac{86}{360}[/tex] × $540 = [tex]\frac{86(540)}{360}[/tex] = $129
