<span>Two adjacent sides of the park say x and y are,
</span><span>x=533feet
y=525feet
A=53º
area=1/2*b*c*sin(A)
111739 feet^2</span>
Answer is C and E.
All of the other ones don't follow order of operations properly.
1. a+3a+4b=5b
2. a+3a=5b-4b
3. 4a=5b-4b
4. 4a=b
a=1/4b
(I think 1/4b is the answer) hope this helps :)
The slope is either 5/2 or 2/5 and the y intercept is 3
