help please: if the answer is not rational round it to the nearest tenth of a unit. "a telephonne pole is supported by a guy wire attached to the top of the pole. the pole is 7 meters tall, above the ground. how long must the guy wire be if it is attached to a rod 6 meters from the bottom of the pole.?"
LET THE POLE BE TB..T AT THE TOP AND B ON GROUND.LET THE GUY WIRE BE AT G ON GROUND
TBG IS A RIGHT ANGLED TRIANGLE
TB=7 M
BG=6 M
TG=? =LENGTH OF GUY WIRE.
TG^2=TB^2+BG^2=7^2+6^2=49+36=85
TG=SQRT (85)=9.2195=9.22 M
