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:
Angle 6 forms a pair of alternative exterior angles with angle 3.
X = 3*15 = 45
Hope it helped.
Step-by-step explanation:
X(x+6) - 6(x+6)
X+6x-6x-36
X-36
