Answer :
Answer:
sec(72.542°) = 3.333
Step-by-step explanation:
given data
cos(theta°) = 0.3
to find out
sec(theta°)
solution
as we know that given equation
cos(theta°) = 0.3
theta° = [tex]cos^{-1} (0.3)[/tex]
theta° = 72.542 .................1
so now we find
sec(theta°)
and we know
sec(theta°) = [tex]\frac{1}{cos (theta)}[/tex] .................2
sec(theta°) = [tex]\frac{1}{cos (72.542)}[/tex] ..............3
sec(72.542°) = [tex]\frac{1}{(0.3)}[/tex]
sec(72.542°) = 3.333
