Question

Math help please answer question a and b ( show work please)

Answer 1

Answer:

a) 24 degrees

b) 50 degrees

Step-by-step explanation:

part a : use sine-1

sine-1 = $\frac{opposite}{hypotenuse}$

sine-1 = $\frac{17}{42}$

sine-1 = 0.405

missing angle = 23.89

round to the nearest degree = 23.89 = 24

part b : use cosine-1

cos-1 = $\frac{adjacent}{hypotenuse}$

cos-1 = $\frac{16}{25}$

cos-1 = 0.64

missing angle = 50.208

round to the nearest degree = 50.208 = 50
