Step-by-step explanation:
let : y = Opponent side, x= Adjecent side
and r= hypotenuse
tan 0 = 4/5
y/x = 4/5 => y =4, x=5
so, r = √4²+5²=√16+25=√41
sin = y/r = 4/ √41
cos = x/r = 5/√41
tan = y/x = 4/5
csc = r/y = √41 /4
sec = r/x = √41 /5
cot = x/y = 5/4
If n = number of African animals then,
n/2 +45 = 172
n/2 = 127
n = 254 animals

Step-by-step explanation:
20+20=40
40/2=20
40-20=20
another way:
