anonymous one year ago A utility worker is installing a 25-foot pole AB at the foot of a hill. Two guy wires, AC and AD, will help keep the pole vertical. To the nearest inch, what is the length of AC?AD is perpendicular to the hill, which makes an angle of 28° with a horizontal line. To the nearest inch, how long should this guy wire be? http://cds.flipswitch.com/tools/asset/media/110896

so you can use sine again to find AD

8. anonymous

$\sin 62°=\frac{ AD }{ 25 }$

9. anonymous

so once you find that you convert in to feet and inches
