hi guys if u could help me with these problems i would be really happy

 

1. A quadrilateral has sides 1, 5, 5, 7, and its area is 16.

What is the product of lengths of its diagonals?

 

2. In a triangle a median, an altitude, and an angle bisector are drawn from the same vertex. All three have different lengths.

Which of them is the longest? (there can be multiple possibilities)

 

3. A triangle has side lengths 3, 4, 5. What is the radius of its inscribed circle? (there can be multiple possibilities)
