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)
