To secure a 610meter radio tower against high winds, guy wires are attached to a ring on the tower. The ring is 7 meters from the top. The wires form a 69o angle with the ground. To the nearest hundredth meter find the length of the guy wire

Make a sketch to see that
sin 69° = 603/L
L = 603/sin69 = appr 562.95 m
