To find the missing angle in a triangle using the Law of Sines, we need more information than just two sides (20 and 25). The Law of Sines states:
\[
\frac{a}{\sin(A)} = \frac{b}{\sin(B)} = \frac{c}{\sin(C)}
\]
Where \(a\), \(b\), and \(c\) are the lengths of the sides opposite to angles \(A\), \(B\), and \(C\), respectively. To proceed, we need to know at least one angle or the lengths of the third side.
Since the problem states "triangle with 20, 25", we can assume those are the lengths of two sides, but without additional information (like the angle between them or the length of the third side), we can't solve for the missing angle directly.
If you can provide the missing angle \(A\) opposite one of the provided sides or the third side, I could help you calculate the remaining angle using the Law of Sines.
