Final answer:
The magnitude of vector l can be found using the Pythagorean theorem and the given direction and length.
Step-by-step explanation:
The magnitude of a vector can be found using the Pythagorean theorem. Given that vector l is 303 degrees long in the 205-degree direction, we can find the magnitude as follows:
Magnitude = √(303^2 + 205^2)
Therefore, the magnitude of vector l is √(303^2 + 205^2).
