Odpowiedź:

a )

1.    β = 360°° - 300° = 60°

α = β : 2 = 30°

------------------------

2.                  2*80° = 160°

  β = 360° - 160° = 200°

-------------------------------------

3.   360° - 230° = 130°

     γ = 130° : 2 =  65°

------------------------------------

4.     δ = 2*87° = 174°

=======================

b )    1.    0,5 α = (  180° - 45° ) : 2 = 135° : 2

więc  α  = 135°

-------------------------

2.

β = 90° - 50° = 40°

----------------------------

3.

γ = 90° - 30° = 60°

----------------------------

4.

180° - 70° = 110°

δ =  ( 180° - 110° ) : 2 = 35°
