You know that
.. tan(a) = 78'/36'
.. a = arctan(78/36) ≈ 65.22°

You also know that
.. a = c = k = j
and that
.. a +c +e = 180°
.. e = g = 180° -2a = 49.55°

f = h = 180° -e = 130.45°

Of course the other corner angles are
.. b = d = i = l = 90° -a = 24.78°

One bit of trigonometry and the rest is arithmetic.
