Find the height of the pole where the guy wire is attached to the nearest tenth of a metre.
Sorry there is no pic.
If the guy wire(c,10m) is the hypotenuse and the ground(a,2m) is one of the legs , then the pole(b) is the second leg.To do this we need the work.
square root of 96 =9.78 something,something,something,something
Round to the nearest meter to get 9.8m2
Again sorry about no pics I couldn't get onto my textbook (server lost) or something like that
