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
