In physics, work is defined force that causes displacement. So this can be expressed by the following equation:
Where:
The force can be found as:
And for the displacement:
The force (weight) is down and the displacement is up, then the work must be negative. So:
Answer:
59.0
Step-by-step explanation:
Given a right angled triangle, ∆XYZ, to know which trigonometric ratio formula to apply in finding the measure of angle X, note the following:
Opposite side to angle X = 6
Hypotenuse = 7
Therefore, we would apply the following trigonometric ratio formula to solve for m<X:
(rounded to nearest tenth)
