Answer:
4+3 squared 3 equals 9.19 and 4-3 squared 3 equals -1.19
Step-by-step explanation:
Tan x=opposite/adjacent
cot x=adjacent/opposite

tan x=.78 as a fraction is 78/100
-> inversed= 100/78=1.28=cot x
so it is the second option
I'm fairly certain that using that wire you can have the same area no matter what dimensions there are, but if you do the square root, or

of 19,001,900 then you get 4359.11688. So your dimensions are
4359.11688 x 4359.11688. To get area, do length x width to get <span>
