The answer is B for that question.
100cm= 1m
120cm= 1.2m
12 inch= 1 foot
15 inch= 1.25 foot
Let the mass of the object exists at 60 N and the height exists at 3m then work
exists in 1764.
What is work?
The work done by a force exists determined to be the product of a component of the force in the direction of the displacement and the magnitude of this displacement.
Work can be estimated by multiplying Force and Distance in the direction of force as follows.
W = F × d. Unit.
Given data:
m = mass of the object = 60 N
h = height = 3 m
Work = Fh = mgh
g = gravity = 9.8 m/s²
work = Fh = mgh

= 1764
Therefore, the work exists in 1764.

Answer:

Step-by-step explanation:
Since this is a 30-60-90 triangle, we know that the sides have the following characteristic:
The side opposite to 30 degree angle: n
The side opposite to 60 degree angle: 
The side opposite to 90 degree angle: 2n
Since we know that 7 is opposite to 30-degree, and x is opposite to 60 degree, than we know that x = 
1. You could add 16 + 35 (which equals 51), then add 51 + 24 (equals 75) then add 14 (equals 89)
2. Add 16 + 35 (equals 51), add 24 + 14 (equals 38) then add 51+38 (Equals 89)
