Question 1108903
{{{system(150*sin(53)/cos(53)+6,or,150*tan(53)+6)}}}


y, vertical disance up building without the 6 feet of observer's height
r, distance from observer eyes to top of building


{{{cos(53)=150/r}}}
{{{r=150/cos(53)}}}
-
{{{y/r=sin(53)}}}
{{{y=r*sin(53)}}}
{{{y=(150/cos(53))*sin(53)}}}
{{{y=150(sin(53)/cos(53))}}}
-
Looking for {{{y+6}}};
