Question 70380
can you help with this wordproblem....A telephone pole is 55 feet tall. A guy wire 80 feet long is attached from the ground to the top of the pole.Find the angle between the wire and the pole to the nearest degree.
|\ You have an adjacent side of a right triangle in the telephone pole: 55 ft.
You have a hypotenuse of a right triangle in the guy wire: 80 ft
cosine=adjacent/hypotenuse
{{{cos(x)=55/80}}}
{{{x=cos^(-1)(55/80)}}}
Put that in your calculator and make sure you're in degree mode.
{{{x=46.56946344}}}  Round to the nearest degree.
{{{highlight(x=47)}}}
Happy Calculating!!!!
