zad 20

a) 180-121=59

180-35=155

180-132=44

180-90=90

b)

180-(76+22)=180-98=82

180-(86+58)=180-144=36

180-(10+45+45)=180-100=80

180-(42+40+28)=180-110=70

c)

180-102=78  78:2=39

B+B+124=180

2b+124=180

2b=180-124

2b=56

b=28

4y+6y=180

10y=180

y=18

4y=4*18=72

6y=6*18=108

2g+3g+45+g+g-5=180

7g+40=180

7g=180-40

7g=120

g=20

2g=40

3g+45=105

g-5=15
