The objective is to write v in the form (|v|cos theta,|v|sin theta) but first we must find the magnitude of vector v and express the answer in radical form!

the vector is: (-7, 8)

would it be ||v||= sqrt (-7)^2+(8)^2 = sqrt 113?

thank you! is that how we'd show the work to get to the sqrt of 113 as well?! @cwrw238
