Solution
Solution Steps
Step 1: Find the components of each vector
The red vector goes from (0,0) to (6,3), so its components are <6,3>.
The blue vector goes from (0,0) to (5,3), so its components are <5,3>.
Step 2: Add the components of the vectors
The resultant vector's components are the sum of the components of the red and blue vectors: <6+5, 3+3> = <11,6>
Step 3: Find the magnitude of the resultant vector.
The magnitude of the vector <11,6> is $\sqrt{11^2+6^2} = \sqrt{121+36}=\sqrt{157}$.
Final Answer:
The magnitude of the resultant vector is $\sqrt{157}$.
