Answer:
8
Step-by-step explanation:
Why?
Because if you draw a line from A to D to make a triangle AED, then triangle all angle add up equal 180.
10.5 grams equals to 0.0105 kilograms
Let <em>x</em> = 3.191919…. Then 100<em>x</em> = 319.191919…, and we have
100<em>x</em> - <em>x</em> = 319.191919… - 3.191919…
99<em>x</em> = 316
<em>x</em> = 316/99
Next, we have
316 = 297 + 19 = 3 × 99 + 19
so
316/99 = (3 × 99 + 19)/99 = 3 + 19/99
