Question

do tihs and show work

Answer 1

$(i) \: \: tan \: 28 = \frac{x}{8} \\ \\ 0.53171 = \frac{x}{8} \\ \\ 0.53171 \times 8 = x \\ \\ 4.25 = x$

$(ii) \: \: tan \: 28 = \frac{8}{x} \\ \\ 0.53171 = \frac{8}{x} \\ \\ x = \frac{8}{0.53171} \\ \\ x = 15.05$

$(iii) \: \: tan \: x = \frac{4}{5} \\ \\ tan \: x = 0.8 \\ \\ tan \: 39 = 0.8$
