Bantuin ya kak nomor 2 dan 3

2]a)
tan a = 3/4
cos a = 4/5
sin a = 3/5
cotan a = 4/3
secan a = 5/4
cosec a = 5/3

b]
sin b = 12/13
cos b = 5/13
tan b = 12/5
cotan b = 5/12
secan b = 13/5
cosec b = 13/12

c]
cos y = 0,8 = 4/5
sin y = 3/5 = 0,6
tan y = 3/4 = 0,75
cotan y = 4/3 = 1,33
secan y = 5/4 = 1,25
cosec y = 5/3 = 1,67

d]
cotan a = 2
tan a = 1/2
cos a = 2/5 V5
sin a = 1/5 V5
cosec a = V5
secan a = 1/2 V5

3]
cos a = 15/17
sin a = 8/17
tan a = 8/15

sin a + tan a
= 8/17 + 8/15
= 120/255 + 136/255
= 256/255
= 1 1/255
