the triangle created is 30-60-90 so since the shortest side is 1 meter, then the hypotenuse (the see saw) should be twice that or 2 meters.

thank you but i was looking for a answer that would have todo with sin cos and tan

anonymous · Answer

ok, since sin(30 degrees) = 1/x, then x = 1/sin(30 degrees)

anonymous · Answer

sin30 = 1/x
=> x = 1/sin30 = 2m
