ur good haha

:D ok, so how you think we can calculate the base?
anonymous
  • anonymous
150 times 40
anonymous
  • anonymous
mmmm.... 150 is heght and 40º an angle, i dont think that will give us the base...
anonymous
  • anonymous
sorry, that is incorrect. you have to use 2(tan theta)
anonymous
  • anonymous
where theta is 90 - 40
anonymous
  • anonymous
50
anonymous
  • anonymous
100

  • anonymous
i get: \[b=2\times 150\times tan(20º) \approx 109.2ft\]
anonymous
  • anonymous
wait so 109.2ft is the answer
anonymous
  • anonymous
do you have an answer for this question ?
anonymous
  • anonymous
that is what i get...
anonymous
  • anonymous
so that the diameter right
anonymous
  • anonymous
oh! i calculated the radius!! so d=2r=218.4ft sorry...
anonymous
  • anonymous

anonymous
  • anonymous
