Answer:
8 is a perfect cube
Step-by-step explanation:
8 = 2^3
We can calculate a side of a triangle if the side's opposite angle, another side and its opposite angle are known using the Sine rule:
a/sin(A) = b/sin(B) = c/sin(C)

n is unknown.
Answer:
799 feet
Step-by-step explanation:
We solve using the Trigonometric function of Tangent.
tan theta = Opposite /Adjacent
From the above question, we have the height of the surveyor = 5.5 feet
theta = Angle of elevation = 65°
Adjacent = 370 feet
Let Opposite = height + height of spider rock
tan 65° = h - 5.5 /370 feet
Cross Multiply
tan 65° × 370 feet = h - 5.5
793.46756059 feet = h - 5.5
h = 793.46756059 feet + 5.5
h = 798.96756059 feet
Approximately = 799 feet
The height of the Spider rock = 799 feet
