You have not specified whether to use degrees or radians. Here are a few rules you should know, though

If \(\tan(a)=x\Rightarrow\tan^{-1}(x)=a\)

If \(\sin(a)=x\Rightarrow\sin^{-1}(x)=a\)

This rule is try for cosine as well.

Therefore, we can solve for a by using the inverse tangent function on the calculators.

\(\tan(a)=1.7124\Rightarrow\tan^{-1}(1.7124)=a\)

Degree Mode: \(59.716109581458\)

Radian Mode: \(1.042242728678\)

\(\sin(a)=0.7734\Rightarrow\sin^{-1}(0.7734)=a\)

Degree mode: \(0.013497966524\)

Radian mode: \(0.698572106543\)
