1. Amatilah gambar di samping. Tentukan perbandingam trigonometri untuk sedut a dan b ( sin, cos, tan, csc, sec, cot) dari segitiga siku-siku di samping.
x = 5
y = 12
z = √(5²+12²)
z = √169
z = 13
sin A = x/ z
sin A = 5/13 ✔️
cos A = y/z
cos A = 12/13 ✔️
tan A = x/y
tan A = 5/12 ✔️
csc A = z/x
csc A = 13/5 ✔️
sec A = z/y
sec A = 13/12 ✔️
cot A = y/z
cot A = 12/5 ✔️
sin B = y/z
sin B = 12/13 ✔️
cos B = x/z
cos B = 5/13 ✔️
tan B = y/z
tan B = 12/5 ✔️
csc B = z/y
csc B = 13/12 ✔️
sec B = z/x
sec B = 13/5 ✔️
cot B = z/y
cot B = 5/12 ✔️
