Exponential form: F(x)= 3/125^x+1
Original voltage: 3/125 of a volt
Notice this is a geometric progression since each number multiplied by some factor equals the next number in the sequence, in this case,

Then by applying the formula for sum to infinity of a geometric progression,
Answer:
90
Step-by-step explanation:
the colums add up to angle 1, which make angle 2 adjacent.
