The solution of the formula for E is given by:
E = 50m/L.
<h3>How to solve an expression for a variable?</h3>
To solve an expression for a variable, we have to isolate the variable.
In this problem, the expression is given by:
L = 50m/E
Hence we do the operations to isolate E, as follows:
LE = 50m
E = 50m/L.

Step-by-step explanation:
2 right triangles are formed.
x is the angle btw wire and grnd
tan x = 10/5 = 2
tanx = ht of tower/(5+14)
2 = tower ht/19
tower ht = 38
length of wire =
