I will do of these,

for 135° :
assume the axle is 20.5 above the ground

height above axle:
sin135 = h/20.5
h = 20.5sin135 = appr 14.5 m
so height above the ground = 20.5 + 14.5 = 35

for 315°

height from axle :
sin 315 = h/20.5
h = 20.5sin135 = appr - 14.5
notice the position would be BELOW the axle
so height above ground = 20.5 - 14.5 = 6 m
