Answer
# Explanation:
## Step1: Calculate $\sin^{-1}(\frac{2}{3})$
Use a scientific - calculator in degree mode. Enter $\sin^{-1}(\frac{2}{3})$. The result is approximately $42^{\circ}$.
## Step2: Calculate $\tan^{-1}(4)$
Use a scientific - calculator in degree mode. Enter $\tan^{-1}(4)$. The result is approximately $76^{\circ}$.
## Step3: Calculate $\cos^{-1}(0.1)$
Use a scientific - calculator in degree mode. Enter $\cos^{-1}(0.1)$. The result is approximately $84^{\circ}$.
# Answer:
$\sin^{-1}(\frac{2}{3}) = 42^{\circ}$
$\tan^{-1}(4)=76^{\circ}$
$\cos^{-1}(0.1)=84^{\circ}$
