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

Vector A = (2x-y)m and Vector B= (x+ay)m (a is alpha, m is meters)

If |A+B|=5m, determine the possible values of a.

2. Relevant equations

The magnitude of A= sqrt 5

3. The attempt at a solution

|A^2 + B^2|=5^2

|(2x-y)^2 + (x+ay)^2|= 5^2

|(2x-y)^2 + (x+ay)^2|= 25

I cannot figure out how to solve this problem. Please help!
