Two wires support an electricity pole as shown in Fig. 5.17.if the wires make angles of 58 and 67 with the ground and /AB/= 21m calculate the lengths of the wires

Answer 1

no diagram. But if you remember your basic trig functions, then if the height of the pole is h, and the wires are on opposite sides of the pole, then
h cot58° + h cot 67° = 21
h = 20
So the wire lengths are 23.6 and 21.7 meters
