Answer:
1). a = 9.42 m
2). b = 6.37 m
3). c = 4.48 m
Step-by-step explanation:
In the figure attached,
By applying tangent rule in triangle ADE,
tan47 =
c =
c =
c = 4.476
c ≈ 4.48 m
Now we apply the same rule in triangle ACE,
tan37° =
b =
b =
b = 6.37 m
Now apply the tangent in triangle ABE,
tan27° =
a =
a =
a = 9.42 m
