Answer:
m∠B = 43°
b = 26.1
c = 38.3
Explanation:
By applying triangle sum in the given triangle,
47° + 90° + m∠B = 180°
137° + m∠B = 180°
m∠B = 43°
By applying sine ratio to the angle measuring 47°.
sin(47°) =

=

c =

c = 38.28
c ≈ 38.3
By applying cosine rule,
cos(47°) =

=

=

b = 38.3[cos(47°)]
b = 26.1
