' = menit
" = detik
1) 2(1/3)° = 7/3° = 7/3 x 60 = 140 '
2) 150 ' = 150/60 = 15/6 = 2(3/6) °
3) 1/4 Π rad = 1/4 x 360° = 90°
4) 2/5 putran = 2/5 x 360 = 144°
5) 240 ° = 240/360 = 6/9 putrn.
6 & 7 coba hitung pelan" psti bisa..
8) 90°-47° = 43
9)180-98 = 72
10)90° - (36+2...) = g kelihatan angkanya 2 brp itu g jlas.. cba hitung sndri psti bs..
11) 2m + 4 m = 90 (ingat sudut siku" nilainya psti 90°)
6m = 90
m = 90/6 = 30/2 = 15° smga mmbntu.. sabarr ya.. klu bleh tau kls brp ini..
