E.√6
Penjelasan dengan langkah-langkah:
A = 45 derajat
B = 60 derajat
C = 180 - (45 + 60) = 180 - 105 = 75 derajat(gk usah dianggap/lupakan)
a = 2
b = ?
a/SinA = b/Sin B
2/sin 45 = b/sin 60
2/(1/2√2) = b/(1/2√3) kalikan silang
b = (2 . 1/2√3)/(1/2√2)
b = √3/(1/2√2)
b = √3/(1/2√2) * (1/2√2)/(1/2√2)
b = (1/2 √6)/(1/4 * 2)
b = (1/2 √6)/(1/2)
b = 1/2 √6 * (2/1)
b = √6
(E)
