Answer:
[tex]1) z = \: 49.9 \\ 2)c = 70.5 \\ 3)t = 71.6 \\ 4)q = 51.1[/tex]
Step-by-step explanation:
sin x = opposite/hypotenuse
cos x = adjacent/hypotenuse
tan x = opposite/adjacent
[tex]1) \cos(x) = \frac{10.3}{16} \\ x = 49.9 \\ \\ 2) \cos(x) = \frac{5}{15} \\ x = 70.5\\ \\ 3) \tan(x) = \frac{12}{4} \\ x = 71.6 \\ \\ \\ 4) \sin(x) = \frac{7}{9} \\ x = 51.1[/tex]
