Yang bisa jawab saya jadiin jawaban terbaik dehhh
Penjelasan dengan langkah-langkah:
a) BC = r = √(x²+y²)
BC = √(4²+3²) = √(16+9) = √25 = 5
b) sin @ = y/r = 3/5
c) cos @ = x/r = 4/5
d) tan @ = ¾
e) cosec @ = 1/sin @ = 5/3
f) sec @ = 1/cos @ = 5/4
g) cotan @ = 1/tan @ = 4/3
Penjelasan dengan langkah-langkah:
AC = 3cm
AB = 4cm
a. BC = √(3²+4²)
= 5 cm
b. sin α = AC / BC
= 3/5
c. cos α = AB / BC
= 4/5
d. tan α = AC / AB
= 3/4
e. cosec α = BC / AC
= 5/3
f. sec α = BC / AB
= 5/4
g. cot α = AB / AC
= 4/3
