B = 58.7°

b = 15.9 ft

a = 9.7 ft

Step-by-step explanation:

We are given;

C = 90°

A = 31.3°

c = 18.6 ft

Since sun of angles in a triangle is 180°, thus; B = 180 - (90 + 31.3)

B = 58.7°

From law of sines, we can find b.

Thus; b/sin B = c/sin C

b/sin 58.7 = 18.6/sin 90

b/0.8545 = 18.6/1

b = 18.6 × 0.8545

b = 15.8937 ft

To the nearest tenth gives;

b = 15.9 ft

Similarly;

a/sin A = c/Sin C

a/sin 31.3 = 18.6/sin 90

a/0.5195 = 18.6

a = 18.6 × 0.5195

a = 9.6627

To the nearest tenth gives;

a = 9.7 ft

answer: .75 km
