Question 687930
An advertising Zeppelin is 60 metres above the ground, it is tethered with a wire that makes an angle of 42 degrees to the ground. How long is the wire? 
----
Draw the triangle:
height = 60 metres
hypotenuse = ?
ground angle = 42 degrees
-----
sin(42) = height/hypotenuse
hypot = height/sin(42)
hypot = 60/sin(42) = 89.67 metres
