Jika diketahui cos@,=7/25 tentukan nilai perbandingan trigonometri lainnya

Kelas 10 Matematika
Bab Trigonometri

cos a = 7/25 → x/r

y = √(r² - x²)
y = √(25² - 7²)
y = √(625 - 49)
y = √576
y = 24

sin a = y/r
sin a = 24/25

tan a = y/x
tan a = 24/7

cosec a = r/y
cosec a = 25/24

sec a = r/x
sec a = 25/7

cotan a = x/y
cotan a = 7/24
