Tentukan nilai sin, cos, dan tan dari titik berikut. a. P (5 , 12) b. Q (7 , 24) Tolong bantuannya saya belum faham betul materi SMA matematika. Tolong bantuann

Bab Trigonometri
Matematika SMA Kelas X

a] P(5, 12)
x = 5, y = 12

r = √(x² + y²)
r = √(5² + 12²)
r = 13

sin a = y/r = 12/13
cos a = x/r = 5/13
tan a = y/x = 12/5

b] (7, 24)
x = 7, y = 24

r = √(x² + y²)
r = √(7² + 24²)
r = 25

sin a = y/r = 24/25
cos a = x/r = 7/25
tan a = y/x = 24/7
