Do you need the angle?

OpenStudy (john_es):

And you need Vx and Vi? Is this is the case, then you can use the relations, \[\tan 63=\frac{16.12}{Vxi}\]Then, when you know the value of Vxi, you can calculate the valur of Vi, using Pitagorean theorem, \[\sqrt{16.12^2+Vxi^2}=Vi\]

OpenStudy (anonymous):

is the value of vx 94.96

OpenStudy (john_es):

The value I obtain for the variable Vxi you draw is \[Vxi=\frac{16.12}{\tan(63)}\]

OpenStudy (john_es):

That is, 8.21.
