a)
[tex] \alpha = 90 \\ \beta = 45[/tex]
b)
[tex] \beta = 30 \\ \alpha =180 - 60= 120[/tex]
c)
[tex] \beta = 80 \\ \alpha = 180 - 160 = 20[/tex]
d)
[tex]180 - 40 = 140 \\ 140 \div 2 = 70[/tex]
[tex] \alpha = 70 \\ \beta = 70[/tex]
e)
[tex]180 - 20 = 160 \\ 160 \div 2 = 80[/tex]
[tex] \alpha = 80 \\ \beta = 80[/tex]
Myślę że pomogłem ;)
