Answer:
Step-by-step explanation:
I believe the only way to solve this is by Heron's Formula.
Add up all the sides and divide by 2 to get the semi-perimeter:
113+100+86 = 299
299/2 = 149.5
Now fill in the rest, which looks like this:

where s is your semiperimeter value, a is the length of one side, b the length of another side, and c the length of the third side:

which simplifies to

which simplifies further to

which, on your calculator, is 4141.49 meters squared (that's rounded to the nearest hundredth).
Answer:
I think its, 5
Step-by-step explanation:
Becaus you take that number and its axcelerated calculation would be 5 in axis square root which is 3 and obviously 3+2 =5 so the wuarterining calculas is 5.

Answer:
For starters for the angles to be complementary they have to be 90 degrees
and angle ECD is a 52 degree angle. Next, you would need to subtract 52 degrees from 90 degrees and get an answer of 38 degrees. Making DCF a 38 degree angle.
Step-by-step explanation:
Divide 83.524 by pi then take half of that answer .
the answer should be 13.29 or 13.3
