Answer:
a) 24 degrees
b) 50 degrees
Step-by-step explanation:
part a : use sine-1
sine-1 = ![\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
sine-1 = ![\frac{17}{42}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B42%7D)
sine-1 = 0.405
missing angle = 23.89
round to the nearest degree = 23.89 = 24
part b : use cosine-1
cos-1 = ![\frac{adjacent}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Badjacent%7D%7Bhypotenuse%7D)
cos-1 = ![\frac{16}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B25%7D)
cos-1 = 0.64
missing angle = 50.208
round to the nearest degree = 50.208 = 50
Your answer is C hope this helps :)
