Question

Can you please help me out ?

Answer 1

45 45 90 triangle
ratio
leg:leg:hypo = x : x : x√2
hypo = 22√2 (x = 22)

so leg = 22

answer
22 units

Answer 2

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)
