Step-by-step explanation:
there is seemingly something wrong with your problem description.
I at least cannot understand your strange symbols at the angles. are that numbers or designators ?
if they are numbers (degrees, right ?), I cannot figure out for sure what they say.
if they are only designators, then we have nothing to work with. we need at least some angles and/or side lengths and distances to calculate some other numbers of the triangles.
