Question

Find the missing angle measure

Answer 1

`\cos(\theta )=\cfrac{\stackrel{adjacent}{322}}{\underset{hypotenuse}{380}} \implies \cos( \theta )= \cfrac{161}{190} \implies \cos^(-1)(~~\cos( \theta )~~) =\cos^(-1)\left( \cfrac{161}{190} \right) \\\\\\ \theta =\cos^(-1)\left( \cfrac{161}{190} \right)\implies \theta \approx 32.07^o`

Make sure your calculator is in Degree mode.
