Answer:
The complete answer is described here below
Explanation:
The answer is indeed 50 N and in the end this boils down to being a trigonometry problem and is solved using pythagorean theorem (A²+B²=C²)
The first thing you have to do is transform your values into vectors (Graphic representation of magnitude (Your value in newtons) and direction (The fact you know they are acting perpendicular to one another)
This will give you two arrows (The vectors) that form a triangle of which you can solve the hypotenuse to sum up both other vectors using the pythagorean theorem.
