## highschoolmom2010 Group Title A blimp provides aerial television views of a football game. The television camera sights the stadium at a 7 degree angle of depression. The altitude of the blimp is 400 m. What is the line-of-sight distance from the television camera to the case of the stadium? Round to the nearest hundred meters. one year ago one year ago

Lets clean it up a bit so we can work on it |dw:1377820572079:dw|

ok

6. timo86m

looks like sin is best here sin(7)=opp/hyp=400/x :)

7. highschoolmom2010

x (sin 7)=400$\frac{ x (\sin 7) }{ \sin 7 }=\frac{ 400 }{ \sin 7 }$

8. highschoolmom2010

$x \approx 3282.2$

FIrst of all sin 7=0.1218 roughly. SO plug it in 0.1218 =400/x cross multipy x = 3284.07 rounding to nearest hundred metter is x = 3284.07 ^ 3300

well was i close enough

11. timo86m

you are correct :D but round

cool thanks @timo86m
