Tentukan nilai x dan nilai perbandingan trigonometri untuk setiap segitiga siku siku berikut!
a.
x² = 26² – 10²
x² = 676 – 100
x² = 576
x = √576
x = 24
Perbandingan trigonometri
sin A = 24/26 = 12/13
cos A = 10/26 = 5/13
tan A = 24/10 = 12/5
cot A = 10/24 = 5/12
sec A = 26/10 = 13/5
cosec A = 26/24 = 13/12
d.
x² = 6² + 8²
x² = 36 + 64
x² = 100
x = √100
x = 10
Perbandingan trigomometri
sin D = 6/10 = 3/5
cos D = 8/10 = 4/5
tan D = 6/8 = 3/4
cot D = 8/6 = 4/3
sec D = 10/8 = 5/4
cosec D = 10/6 = 5/3
