The number is 200 .
10 is 5% of 200
We will have the following:
Using exponential regression we will have that the line of best fit will be:

Now, we will have that:

So, the approximation using linear regression gives us as solution approximately 29.7 years; thus the closest one to match is then
Length of AB is 18
Step-by-step explanation:
- Step 1: Find length of AB when AC = 9√3 and ∠B = 60°. Use trigonometric ratio sine.
sin 60 = opposite side/hypotenuse = 9√3/x
x = 9√3/sin 60
= 9√3/√3/2 = 9√3 × 2/√3 (∵ a ÷ b = a×1/b)
= 18
its all about the angles just subtract the number you have from the total
