<span>When 3 Triangle sides are known:
</span><span>The longest side must be less than the sum of the other 2 sides.
5, 12 and 13 - can be constructed

A compass<span> is an instrument used for navigation and orientation that shows direction relative to the geographic "cardinal directions", or "points".</span>
Sorry I don't have enough time to deal with this problems, I believe that by using this formula you will easily come out with your answer. In the first one that has all sides you must use the law of cosines. Here is the formulas . Keep it because it is very helpful
Answer: D
Step-by-step explanation:
We know that the line
is shaded below, so it represents
.
Similarly, the line
is shaded above, so it represents
.
The best to do this is like this:
5 hundred thousand would be 500,000
12 of 10,000 (should be 12,000)
1,000 tens is 10,000 plus 15 tens is 150 so this is 10,150
7 ones
