Answer:
BC ≈ 14.7 m
Step-by-step explanation:
Using the Sine rule in Δ ABC
= 
To find ∠ A subtract the 2 given angles from 180°
∠ A = 180° - (90 + 28)° = 180° - 118° = 62°
Then
=
( cross- multiply )
BC × sin28° = 7.8 × sin62° ( divide both sides by sin28° )
BC =
≈ 14.7 m ( to 3 significant figures )
