Strengthen your trigonometry skills with this worksheet! Solve cosine and sine problems using right triangles. Perfect for mastering trigonometric ratios.

To solve for the missing angle, what trig equation do we set up?

x=sin⁡−1(300400)x=\sin^{-1}\left(\frac{300}{400}\right)x=sin−1(400300​)  

x=cos⁡−1(300400)x=\cos^{-1}\left(\frac{300}{400}\right)x=cos−1(400300​)  

x=tan⁡−1(300400)x=\tan^{-1}\left(\frac{300}{400}\right)x=tan−1(400300​) 

x=tan⁡−1(400300)x=\tan^{-1}\left(\frac{400}{300}\right)x=tan−1(300400​) 

Find the measure of the indicated angle (?) round to the nearest tenth.

Which trigonometric ratio should you use?
