Show your attempt.

well i know to find the totals displacement you need to find the components of each vector so they were 3.83 and 3.21 for the first part and 2.6 and 1.5 for the second part

If you draw the vectors, you can see that which components should be added and which components should be subtracted.

even when i do that i continue to get the wrong answer and I do not know how to figure out the degree measurement
