Odpowiedź:
1. a) a=58, b=360-58-58-126=118
b)a=78, c=180-45=135, d=a=78, b=360-78-78-135=69
c) b=90, a=180-89=91, c=180-27=153, d=360-153-90-91=26
2. a) a=130, b=(360-130-130)/2=50, c=50
b) a=66, c=66, d=(360-66-66)/2=114, b=114
3. a) b=25, a=180-(20+25)=180-45=135, c=135
b)c=(360-56-56)/2=124, a=(180-124)/2=28, b=90-28=62
