4 0
I: 4x - 2y = 8
4 * 0 - 2y = 8
0 - 2y = 8
2y = 0 - 8
2y = -8
y = -8/2
y = -4

II: 4x - 2y = 8
4*2 - 2y = 8
8 - 2y = 8
2y = 8-8
2y = 0
y = 0/2
y = 0

III: 4x - 2y = 8
4 * (-1) - 2y = 8
-4 - 2y = 8
2y = -4-8
2y = -12
y = -12/2
y = -6

<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
