Count the distance d, which gives you 7.
Use Pythogarean theorem to find c:
Plug in the numbers:
c is 5.
Same thing with g:
g equals 5.66.
Domain of: 3x-2
Solution: -Inf < x < Inf
Interval Notation: (-Inf, Inf)
Inf = Infinity (Replace "Inf" with the infinity symbol)
"-" = Negative sign
X = half width of tent
Tan(40) = 6/x
x = 6/Tan(40) = 7.15
2x = 14.30 feet the width of the tent
