using the drawing i got 16 idk if its right

thats right ! 15 ft radius + 1ft overhang = 16

keep going

sorry 1 sec

ok

\[\cos (25)=\frac{ 16 }{ x }\]

i have forgotten what to do next

you wanto find x

maybe multiply x both sides first

\[(x)*\cos25= \frac{ 16 }{ x }*(x)\]
\[X \cos 25=16\]

next ?

\[\frac{ X \cos 25 }{ \cos 25 }=\frac{ 16 }{ \cos 25 }\]

perfect !

\[x=14.5\]

try again

looks uve multiplied cos25, instead of dividing

16.1

try again

*breaking out scientific calculator*

approx 17.6

lol, yes 17.65 ft
but they want the answer in ft and inch

ok so i convert ???

the .65 is confusing me

17.65 ft
17 ft + .65 ft
17 ft + .65 x 12 inch
?

17.65 ft
17 ft + .65 ft
17 ft + .65 x 12 inch
17 ft + 7.8 inch
17 ft 7.8 inches
~ 17 ft 8 inches

wow i feel kinda bad for not knowing that :(

its tricky lol

oh yea
