bantu dong kak ,atau abang soal matematika ini ,mohon bantuan jalannya

Bab Trigonometri
Matematika SMA Kelas X

1] ST = √(RT² - RS²)
ST = √(10² - 6²)
ST = √(100 - 36)
ST = √64
ST = 8 cm

2] sin T = RS/RT
sin T = 6/10
sin T = 3/5

cos T = ST/RT
cos T = 8/10
cos T = 4/5

tan T = RS/ST
tan T = 6/8
tan T = 3/4

cosec T = 1/sin T
cosec T = 5/3

sec T = 1/cos T
sec T = 5/4

cotan T = 1/tan T
cotan T = 4/3
