Tolong saya dong bang. cariin jawaban dan caranya ​

Penjelasan dengan langkah-langkah:

i] (2 . tan 30°)/(1 + (tan 30°)²)

= (2 . 1/3 √3) / (1 + (1/√3)²)

= (2/3 √3) / (1 + 1/3)

= (2/3 √3) / (4/3)

= 2/4 √3

= 1/2 √3

= sin 60°

ii] (1 – (tan 45°)²)/(1 + (tan 45°)²)

= (1 – (1)²) / (1 + (1)²)

= (1 – 1) / (1 + 1)

= 0/2

= 0
