the house, the ground, and the flagpole form a right triangle with the flagpole being the hypotenuse
use cosine
cos=adj/hyp
cos(54º)=x/30 where x=distance the base of the flagpole is from the house
using a calculator, table of values, or the web..
0.58778525=x/30
30*0.58778525=x
x=17.633 feet (distance from base to house)
