Answer:
[tex]29.98\°[/tex]
Step-by-step explanation:
Let
x-----> the angle between the longest side and the diagonal
we know that
The tangent of angle x is equal to the ratio of smaller side to the longer side of rectangle
[tex]tan(x)=\frac{577}{1,000}[/tex]
[tex]x=arctan(\frac{577}{1,000})=29.98\°[/tex]
