you simply have to add all of the numbers together, so it'll be 2+5+12+7+1 or 27, therefore the answer is B
Since this is a scalene triangle, two sides will equal the same, meaning two angles will equal the same. So 70 has an equal on the other side, meaning 70+70=140, and x will equal the remainder, meaning x=40.
Hope that helps.

<u>Answer:</u>
0.0005 oz
<u>Step-by-step explanation:</u>
Usually, the greatest number that is allowed for approximation, assuming that the number itself is obtained by approximation, is the greatest possible error of it.
It is normally half the place value of the last digit in a number.
Like here we have 
oz which is equal to 
oz. The last digit is 5 which is at the thousandth place (0.001) so the greatest possible error for this would be its half.
= 0.0005 oz
