## Algebra 2 (1st Edition)

$1.20$ radians and $68.90^{\circ}$
We are given that $\cos^{-1} (0.36)$ In order to get the answer in radians, we need to put the calculator in radians mode. Then, our result will be: $1.20$ radians In order to get the answer in degrees, we need to put the calculator in degrees mode. Then, our result will be: $68.90^{\circ}$
