Calculate cos, sin and tan of an angle Trigonometry

Find the \cos\left(a\right) in the following triangle:

\cos\left(a\right)=\dfrac{4}{3}

\cos\left(a\right)=\dfrac{3}{4}

\cos\left(a\right)=\dfrac{4}{5}

\cos\left(a\right)=\dfrac{3}{5}

Find the \cos\left(a\right) in the following triangle:

\cos\left(a\right)=\dfrac{1}{3}

\cos\left(a\right)=\dfrac{4}{\sqrt{2}}

\cos\left(a\right)=8\sqrt{2}

\cos\left(a\right)=3

Find the \tan\left(a\right) in the following triangle:

\tan \left(a\right) = \dfrac{5}{3}

\tan \left(a\right) = 0.6

\tan \left(a\right) = \dfrac{\sqrt{34}}{15}

\tan \left(a\right) = \dfrac{\sqrt{34}}{3}

Find the \sin \left(a\right) in the following triangle:

\sin \left(a\right) = \dfrac{2}{3}

\sin \left(a\right) = \dfrac{5}{6}

\sin \left(a\right) = 1.5

\sin \left(a\right) = 1.2

Find the \tan \left(a\right) in the following triangle:

\tan \left(a\right) = 1

\tan \left(a\right) = \sqrt{2}

\tan \left(a\right) = \dfrac{1}{\sqrt{2}}

\tan \left(a\right) = 4\sqrt{2}

Find the \sin \left(a\right) in the following triangle:

\sin \left(a\right) = \dfrac{2\sqrt{6}}{7}

\sin \left(a\right) = 14\sqrt{6}

\sin \left(a\right) = \dfrac{7}{5}

\sin \left(a\right) = \dfrac{7}{2\sqrt{6}}

Find the \cos\left(a\right) in the following triangle:

\cos \left(a\right) = \dfrac{\sqrt{3}}{3}
