elixir [45]

Answer:

  C. 3

Step-by-step explanation:

You know the angle sum is ...

  ∠FGT +∠TGH = ∠FGH

You can use this relation with the given values to find x.

 90 + (8x +4) = 39x +1

  93 = 31x . . . . . . . . . . . . . add -1-8x, collect terms

What is the equivalent decimal to this fraction? 10/45 0.2 0.222222222... 0.232323232323... 0.181818181818...​
Ivan

Factorize the numerator and denominator, then simplify:

10/45 = (2×5)/(9×5) = 2/9

Now,

1/9 = 1/10 + 1/90

1/90 = 1/10 × 1/9 = 1/10 × (1/10 + 1/90) = 1/100 + 1/900

1/900 = 1/100 × 1/9 = 1/100 × (1/10 + 1/90) = 1/1000 + 1/9000

and so on, which is to say

1/9 = 1/10 + 1/100 + 1/1000 + …

or

1/9 = 0.111…

so that multiplying both sides by 2 gives

2/9 = 0.222…
