Zad. 13
Po kolei:
360°-90° = 270°
180°-47° = 133°
360°-128° = 232°
360°-24°= 336°
Zad. 14
S=y
180° = 50+S+y
130° = S+y
S=65°
[tex] \gamma [/tex]
=65°
[tex] \beta [/tex]
= 50°
[tex] \alpha [/tex]
= 65°
Zad. 15
[tex]\alpha + \beta = 180[/tex]
[tex]2 \beta = \alpha [/tex]
[tex] \alpha = 120[/tex]
[tex] \beta = 60[/tex]
S=B=60°
[tex] \gamma = 180 - 90 - 60 = 30[/tex]
