(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A vector of magnitude 20 is added to a vector of magnitude 25. The magnitude of this sum might be:

a. zero

b. 3

c. 12

d. 47

e. 50

2. Relevant equations

c ^2 = a^2 + b^2

3. The attempt at a solution

I was not entirely sure on what to do. I tried using the Pythagorean theorem to find the resultant of the 2 vectors and got 32. ( c ^2 = 20^2 + 25^2).

The answer by the way is C.

Thanks!

Joe
