PEMDAS ( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
4(2.53(207))
Since there are no equations in the parentheses, or exponents, we skip these, and head straight for multiplication:
4(523.7)
Then, do multiplication again:
2094.8
So that means, 4(2.53(207)) = 2094.8
I assume the brackets mean parentheses, since the absolute value of 523.7 does not mean anything in this equation.
for this case we have to define trigonometric relations of rectangular triangles, that the tangent of an angle is given by the leg opposite the angle on the leg adjacent to the angle. So:

Answer:

$42019.25 because you subtract 1-0.0765=0.9235 then you multiply that by $45500 to get a total paycheck of $<span>42019.25</span>
