Soal no 3 tolong dibantu jawab kakak

Jawab
a= 46°25' 48"
a = 45°85'48 '
a = 45° 84' 108"

b = 26° 53' 14"
b = 26° 52' (60 +14)"
b = 26° 52' 74"

a) 1 1/3 a = 4/3 a 
= 4/3 (45° 84' 108")
= 4(15° 28' 36")
= 60° 112' 144"
= 60° (60 +52)' (120 + 24)"
 = 60° + 1° + 52' + 2' + 24"
= 61° + 54' + 24"

b) 2a  - 1 1/2 b =
= 2a – 3/2 b 
= 2 (46° 25' 48") – 3/2 (26°52'74")
= 92° 50' 96" – 3(13° 26' 37")
= 92°50' 96" – 39° 78' 111"
= 92° 50' 96" – 39° (60+18)' (60+51)"
= 92°+50' +96 – (40° + 19' + 51")
= 52° + 31'+ 45"
