Please give the right answer and show work if possible

Answer 1

14

Explanation:

Sin(∅) = Opposite angle ÷ hypotenuse.

Sin (45) = 7
`√(2)` ÷ hypotenuse

hypotenuse = 7
`√(2)` ÷ sin(45)

*********************

Keep in mind

sin(45) = √2÷2

*********************

so we have: Hypotenuse = 7√2 ÷ (√2÷2)

Hypotenuse= 14.
