Question

Determine the missing side lengths​

Answer 1

base =3in and hypotenuse =3√2

Explanation:

relationship between perpendicular and hypotenuse is given by sin angle

sin 45=p/h

sin45=3in/h

h=3in/sin45=3√2 inch

relationship between perpendicular and base is given by tan angle

tan45=P/b

b=3in/tan45=3in

Answer 2

Given that is a 45-45 triangle, the hypotenuse should be x
`√(2)`, so in this case. The hypotenuse should be 3
`√(2)`, and the other side lengths 3. I see no other way of it going other than that one; I hope I helped at least a bit!
