1) Split the second term in 
into two terms.
2) Factor out common terms in the first two terms, then in the last two terms.
3) Factor out the common term 
16 x 6 = 96
96 - 7 = 89
or
14 pizzas and 5 slices
Answer : 89 slices

<h3>Answer</h3>
a = 36
b = √3/5
════════════════════
<h3>Known </h3>
Adjuscent = 12√3
════════════════════
<h3>Question</h3>
Opposite = ?
Hypotenuse = ?
════════════════════
<h3>Way to do</h3>
• finding a - opposite
#use tan formula
tan(∅) = opposite / adjuscent
tan(60) = opposite / 12√3
opposite = tan(60) × 12√3
opposite = 36
•finding b - hypotenuse
#use cos formula
cos(∅) = adjuscent / hypotenuse
cos(60) = 12√3 / hypotenuse
hypotenuse = 12√3 : cos(60)
hypotenuse = √3/5
