The magnitude of the sum of two vectors is expressed as:

$\overline{){\mathbf{R}}{\mathbf{=}}\mathbf{\left|}\stackrel{\mathbf{\rightharpoonup}}{\mathbf{A}}\mathbf{\right|}{\mathbf{+}}\mathbf{\left|}\stackrel{\mathbf{\rightharpoonup}}{\mathbf{B}}\mathbf{\right|}}$

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
