Question

Sudut terkecil dari 04.30, 07.20 dan 05.12

Answer 1

04.30 = 4 30/60 x 30*
= 4×30* + 30/60×30*
= 120* + 15*
= 135*

= 6 × 30*
= 180*

= 180* - 135*
= 45*

07.20 = 7 20/60 × 30*
= 7×30* + 20/60×30*
= 210* + 10*
= 220*

= 4 × 30*
= 120*

= 220* - 120*
= 100*

05.12 = 5 12/60 × 30*
= 5×30* + 12/60×30*
= 150* + 6*
= 156*

= 2 × 30*
= 60*

2 menit = 2 × 6*
= 12*

= 60* + 12*
= 72*

= 156* + 72*
= 84*
