If we assume the hypotenuse to be "h"
h * cos(90-8) = 3.35
h * cos 82 = 3.35
h = 24.07m
The other base = h * cos 8 = 24.07 * cos 8 = 23.83m
So, lengths of the other two sides will be 24.07m & 23.83m

cos 8° = 3.35 / h
h.cos 8° = 3.35
h = 3.35 / cos8°
h = 3.38 m (hypotenuse----slope length)
sin 8° = y / 3.38
y = 3.38 x sin 8°
y = 0.47 m (vertical height)
