as we know the resulting number starts with 3 and is a 4 digit number so we fix 4 in the thousands position of original number. Subsequently we fix 4 in the hundredth position of the number after subtraction from 738
4_ _ 3 - 738 = 34_ _
now we have a 2 empty spaces and 9 number to choose from, start from the lowest .
4 <u>1 </u> <u>0</u> 3 - 738 = 3365 , 4 has to be in the hundredth position
we increment the middle numbers by four and then by 1 until we get our answer
In order to find the value of angle A, I used the inverse sine function, where I input a ratio between the opposite and hypotenuse: 4/6, and got the answer.
