Answer:
8
Step-by-step explanation:
→ Use trigonometry to find x, we have no hypotenuse so we utilise the TOA formula
TOA = Tan = Opposite ÷ Adjacent
→ The opposite of the triangle is 8√3 and we want to find the adjacent of this triangle so we rearrange
Opposite ÷ Tan
→ Substitute in the values
8√3 ÷ tan(60) = 8
Equilateral triangles always have 3 congruent angles, so the measure of each angle is 60
The given formula is

Therefore

Given:
C = $25,000
V = $12,000
t = 4.5 years
C/V = 0.48
1/t = 0.2222
Therefore

Answer: 15% (nearest integer)
X = 25
a^2 + b^2 = c^2
19^2 +16^ = c^2
617 = c^2
(Square root 617)
x=24.83
x=25
