Answer:
A
Step-by-step explanation:
Using the Sine rule in Δ ABC
= , substitute values
= ( cross- multiply )
BC sin38° = 3 sin66° ( divide both sides by sin38° )
BC = → A
4
The slope form equation is: y=mx+b so once you plug in the numbers available through the diagram you get.
y=3x+4
Answer l=69m
l= A/w= 3657/53=69m
use the formula A=wl
