Question 378725
picture the bottom of the pole at the origin (0,0)
with the pole going up the y-axis , and the top at (0,80)


the equation of the hillside is ___ y = [sin(12º)]x


the equation of the guy wire is ___ y = [sin(-55º)]x + 80


solve for x at the intersection
substitute to find y at the intersection
use the distance formula (from the origin) to find the solution
