ratio
leg:leg:hypo = x : x : x√2
hypo = 22√2 (x = 22)

so leg = 22

What you can do for this case is to use the following trigonometric definition.sine (45) = a / h
 Where,
 a: side of the triangle.
 h: hypotenuse.
 We then have to clear the value of a:
 a = sine (45) * h
 Substituting:
 a = sine (45) * (22 * root (2))
 a = (root (2) / 2) * (22 * root (2))
 a = 22
 Answer:
 22 (option 3)
