    So P is certainly there in the problem? It made no sense to me to include it so I didn't.

    I will need to use one of the formulas that allow to calculate tan if I have cos given, or to calculate the third angle from Pythagorean theorem and then use it to calculate tan

    the third side and you will use the definition from tan which is opp over adj, right?

    @tomektomeknyc I hope that you were able to find the answer before @Haseeb96 gave you the answer. I really hope you had the chance to see if you could get the answer first rather than someone just handing it to you.

    The way he suggested is one way to look at it. You can straight up use one the trig Pythagorean identities. I sorta like using the visual I suggested.
