Zadanie 10
a) wskazówka minutowa
[tex]\frac{15}{60} =\frac{1}{4} \\\\\frac{1}{4}[/tex]* 360° = 90°
[tex]\frac{5}{60} =\frac{1}{12}[/tex]
[tex]\frac{1}{12}[/tex]* 360° = 30°
[tex]\frac{40}{60} =\frac{2}{3}[/tex]
[tex]\frac{2}{3}[/tex]* 360° = 240°
b) wskazówka godzinowa
360° *[tex]\frac{1}{12}[/tex] = 30°
30°*2,5 = 75°
[tex]\frac{60}{10} =6[/tex]
30°: 6= 5°
Zadanie 11
a) 11°°
360° : 12 = 30°
b) 10°°
2 * 30°= 60°
c) 10³⁰
4,5 *30° = 125°
d) 5°°
5 * 30° = 150°
