AC² = AB² + BC²
AC² = 24² + 7²
AC² = 576 + 49
AC² = 625
AC = √625
AC = 25
sin α = BC/AC = 7/25
cos α = AB/AC = 24/25
tan α = BC/AB = 7/24
cosecan α = AC/BC = 25/7
secan α = AC/AB = 25/24
cotangen α = AB/BC = 24/7
2.
tan α = 0,75 = 3/4
y = 3
x = 4
r² = x² + y²
r² = 4² + 3²
r² = 16 + 9
r² = 25
r = √25
r = 5
a. sin α = y/r = 3/5
b. cos α = x/r = 4/5
c. secan α = r/x = 5/4
d. cotangen α = x/y = 4/3
e. cosecan α = r/y = 5/3
