Nilai cosec teta = 25/24. nilai cos teta adalah?

1/sinx = 25/24
25.sinx = 24
sinx = 24/25
cos²x + sin²x = 1
cos²x = 1-sin²x
= 1-(24/25)²
= 625/625 - 576/625
cos²x = 49/625
cos x = ±(7/25)

Cosec = miring/depan =25/24
Cos = samping/ miring

Brarti harus cari sis samping mnggunakan rumus pythagoras
B^2 = A^2 - C^2
= 25^2 - 24^2
= 625 - 576
= 49
B = 7

Berarti cos =7/25
