Answer:
=60 the second option.
Step-by-step explanation:
Given the trigonometric ratio, we can find the value of the angle by simply finding the inverse of the given ratio.
If for example Cos ∅= a, then ∅=Cos⁻¹a
If Cos (x)= 0.5, then x= Cos⁻¹ 0.5
Cos⁻1 0.5=60°
The angle whose sine is 0.5 is ∅=60°
The answer is -20 and you solve by putting it in the calculator
The final amount of the compound interest after 6 years would be $ 294, 122, 500
<h3>How to determine the final amount</h3>
The formula for the final amount is given as;

Where
A = final amount
P = principal interest
r = interest rate
n = number of times
t = time of periods
We have,
A =

A = 
A =
× 
A =$ 
Thus, the final amount of the compound interest after 6 years would be $ 294, 122, 500
