Try to set each  angle up like this:

tan(5): Cosine(5) Sine(5) 

If I understand this correctly.

anonymous · Answer

this is probably the addition angel formula for tangent or sommmat

inexilewetrust · Answer

If you have a scientific calculator (which you should since this is trig)  it would be easier.

anonymous · Answer

in fact that is exactly what it is

anonymous · Answer

some goofy math teacher question, this is the formula for 
$$\tan(\alpha+\beta)$$ wtih $\alpha =5^\circ, \beta=55$ so compute 
$$\tan(60^\circ)$$ and you are done

anonymous · Answer

so, what do i do after i solve tan(60)?

anonymous · Answer

I mainly need help with writing the expression as the sine, cosine, or tangent of an angle.

inexilewetrust · Answer

Do you mean like finding the Cosine of an angle then Sine of the same angle or what exactly? Could you be a bit more specific?

anonymous · Answer

That is why I am confused. All the question say is this exactly:
write the expression as the sine, cosine, or tangent of an angle.
Then the expression given
