...? :s what?

seascorpion1 · Answer

$$\tan(\theta)=\frac{opposite}{adjacent}$$hope this helps.

michele_laino · Answer

hint:
we can write this equation:
$$\huge  11 = 193 \cdot \tan \theta $$

Can you solve it?

Uh. I got 0.0569948186528497

seascorpion1 · Answer

tan(theta)=11/193 so theta=tan^-1(11/193)

seascorpion1 · Answer

What have you got for theta?

seascorpion1 · Answer

You seem to have worked out what tan theta is, do tan inverse of both sides.

michele_laino · Answer

please you have to do this computation:
$$\huge \arctan \left( {0.056994818} \right)$$

michele_laino · Answer

or, using a different, and equivalent notation:
$$\huge {\tan ^{ - 1}}\left( {0.056994818} \right)$$
