For this you have to do sin of 30 degrees so if you have a calculator put sin(30)= a/44 and solve for a
Let the money alleli initially had be x
Money after buying clothes = x-(1/2)x=(1/2)x
Money spent on shoes = (1/2)x × (1/3)x=(1/6)x
Remaining money = x minus( (1/2)x + (1/6)x)= (1/3)x
Also we know the remaining money is 1000
Therefore
(1/3)x = 1000
Multiplying 3 on both sides
X = 3×1000
X = 3000
The initial amount she had is 3000
Hope this is right!!

<h3>What is exponents?</h3>
A symbol written above and to the right of a mathematical expression to indicate the operation of raising to a power.
The given table values satisfied the fourth function.
If we put one by one all the values of x given in a table we get the corresponding value of f(x).
like, if we put -2 we get f(x)= 75 closer to 71
Hence, Exponential model best represents the data is
