Answer:
The value of θ is 20.105°
Step-by-step explanation:
Consider the provided information.
A force of F pounds is required to pull an object weighing W pounds up a ramp inclined at θ degrees from the horizontal.
Sine of angle is force over weight.
Substitute F = 5500 pounds and W = 16,000 pounds in above formula.
Hence, the value of θ is 20.105°
Lets name the shortest piece a, the medium b and the longest c
Together they are 90inches
The longest is 30 inches longer than the shortest
The third piece is half the lenght of the longest
So if you place c=a+30 in the other 2 equasions you get
And
Now if you put this 2 toghether u get
Multyplied by 2
Meaning that a=18inches
Now that we have the lenght of a we put it in the previous equasion
So b=48/2 which means b=24inches
And together they must be 90 so
C=48inches
