Answer:

angle B = 43°

side c = 12.31

side b = 8.40

Step-by-step explanation:

<u>Solve for angle B:</u>

sum of angles in a triangle = 180°

180 - (47+90) = 43°

<u>Solve for side c:</u>

sin(47) = opposite/hypotenuse

sin(47) = 9/c

.731 = 9/c

c = 12.31

<u>Solve for side b:</u>

a^2+b^2 = c^2

9^2 + b^2 = 12.31^2

81 + b^2 = 151.54

b = 8.40
