Find an answer to your question The voltage is 27/125 and it has been reduced 3 times. What is the original voltage in the circuit?
Answer:
3854ft
Step-by-step explanation:
By assuming that the cable is not doubled.
in order to find the length of the base of the mountain
tan74°=3400/x
x= 3400/tan74°
x≈ 975ft
Therefore, the length of the cable equals to
=
length≈ 3854ft
Thus, the shortest length of cable needed is 3854ft
Of the sixteen possibilities only one is HHHT, so the probability is
