Answer:
Great question
Step-by-step explanation:
(5×7)-(5×6) = 5×(7-6)
BC ≈ 14.7 m
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 )
