The length of FD = 0.76 feet.
Step-by-step explanation:
Given that in ΔDEF, the angle F measures 90° and the angle D measures 83° and EF=6.2 feet
To find the length of FD, let us use the tangent function. The tangent of an angle is the length of opposite side divided by the length of the adjacent side.

From the given data, θ=83°,
and 
Substituting these values in the tangent formula, we get,

Using calculator, the value of
and substituting and solving the equation, we get,

Thus, the length of FD = 0.76 feet.
Answer: Fission
Fission is the splitting of nuclei.
Step-by-step explanation:
Keep in mind that a nuclear fission is a nuclear reaction where the nucleus of an atom will be divided into 2 smaller, lighter nuclei.
also the Fission is a way of the nuclear transmutation because the fragments that we are getting, are not the same product as the first or the original atom. The two nuclei that we get are similar but with a slowly different sizes.
the energy that we produce during this process is bigger than we get with all the gasoline of the world, because of the forces through a nuclei is united.
