Hi everyone. Can you help me with my assignment? PLEASE? :D Here's the question A vertical pole of height 20 metres stands on horizontal ground and is supported by a number of guy wires. each wire has one end attached to a point seven-eights of the way up the pole and the other end attached to one of the fastening situated on the ground, 25m from the base of the pole. Find the acute angle each wire makes with the horizontal.

OpenStudy (anonymous):
