Hypothesis (p): A polygon is a square
Conclusion: (q): It is a rectangle
Inverse: q → p <em>If a polygon is a rectangle, then it is a square</em>
Converse: ~p → ~q <em>If a polygon is not a square, then it is not a rectangle.</em>
Contrapositive: ~q → ~p <em>If a polygon is not a rectangle, then it is not a square</em>
Your answers are correct
Answer: 51.9 degrees
Step by step explanation:
Sin(71)/35.6=Sin(x)/21.3
21.3Sin(71)=35.6Sin(x)
21.3Sin(71)/25.6=sin(x)
Sin^-1(21.3Sin(71)/25.6)=x
51.87827502 degrees=x
51.9= angle x
