Cos 60 + Sin 30 / Tan 30 + Cos 30

Kelas 10 Matematika
Bab 6 - Trigonometri Dasar

(cos 60° + sin 30°)/(tan 30° + cos 30°)
= (1/2 + 1/2) / (1/3 . √3 + 1/2 √3)
= 1/((2√3 + 3√3)/(2 . 3))
= 6/(5√6)
= (6√6)/(5 . 6)
= (1/5) √6

=Cos 60 + sin 30/tan 30 + cos 30 =1/2 + 1/2 / 1/3 akar 3 + 1/2 akar 3 = 1/ 5/6akar 3 = 6/ 5 akar 3
