Answer 1

Answer:

<B=39.80

Step-by-step explanation:

tan(b)=5/6

b=$tan^{-1}$(5/6)

b=39.80557109

b=39.80 to the nearest hundredth.

Answer 2

Answer:

$\angle B= 39.81\degree$

Step-by-step explanation:

$\because \tan \angle B = \frac {AC}{BC} \\\\\therefore \tan \angle B = \frac {5}{6} \\\\\therefore \tan \angle B = 0.833333333\\\therefore\angle B= \tan^{-1}(0.833333333)\\\therefore\angle B= 39.805569965\degree \\\huge \purple {\boxed {\therefore\angle B= 39.81\degree}}$
