When you draw your right triangle:
hypotenuse = wire length = 1000ft
The vertical building = length x
The horizontal distance from building base to wire bottom = y
Building Height:
Sine function: sin 43 = opposite/hypotenuse = x/1000
x = 1000 sin 43
x = 682 ft
Distance from tower base to wire:
Cosine function: cos 43 = adjacent/hypotenuse = y=1000
y = 1000 cos 43
y = 731.35 ft
I hope this helps!
