Answer:
The value of x is 17.32
Step-by-step explanation:
It can clearly be seen that the triangle is a right-angled triangle.
In the triangle, according to reference angle 13 degree,
Base = 30
Perpendicular = x
We can use trigonometric ratios for finding the value of x
As tangent includes both perpendicular and base, we can use this.
So,
Rounding off to nearest hundredth
x = 17.32
Hence,
The value of x is 17.32
Answer:
Work done lb-ft
Step-by-step explanation:
The density of the chain in lb/ft is equal to
lb/ft
Total Work done is equal to the summation of work done up to the top of building.
We will use integration for this evaluation.
The mathematical relation is as follows
where "p" is the density
Substituting the given values, we get
Work done lb-ft
