First, to find how high the ladder reaches, we can use tangent.
the formula for the tangent of an angle is
tan(theta)=o/a
the angle is 68, the adjacent side is 2
tan(68)=x/2
multiply by two
2*tan(68)=x
x=4.95 meters
then, to find the length of the ladder (y in the diagram) we can use cosine
cos(theta)= a/h
cos(68) = 2/y
move the equation around a little bit
y = 2/cos(68)
y = 5.34 meters
