4. A communications tower is located at the top of a steep hill, as shown. A guy-wire is to be attached to the top of the tower and to
the ground, 165 m downhill from the base of the tower. The
height of the tower is 80 m, how long is the guy-wire?

If 1 is divided by the sum of y& 4.the result is equal to 3 divided by 4, find the value of m
