Question 1101347
The {{{ 3 }}} ft is called the rise
The distance from center of roof
to where the roof meets the wall
of the house is called the run.
------------------------------
The slope of the roof is [ rise ] / [ run ]
Use Pythagorean theorem
{{{ c^2 = a^2 + b^2
{{{ 16^2 = 3^2 + b^2 }}}
Where {{{ b }}} is the run
{{{ 256 = 9 + b^2 }}}
{{{ b^2 = 247 }}}
{{{ b = 15.7162 }}}
-------------------
slope = {{{ a/b }}}
slope = {{{ 3/15.7162 }}}
slope = {{{ .1909 }}}
