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
