Question

Find the following values from the information given
sec(theta°); cos(theta°) = 0.3

Answer 1

sec(72.542°) = 3.333

Explanation:

given data

cos(theta°) = 0.3

to find out

sec(theta°)

solution

as we know that given equation

cos(theta°) = 0.3

theta° =
`cos^(-1) (0.3)`

theta° = 72.542 .................1

so now we find

sec(theta°)

and we know

sec(theta°) =
`(1)/(cos (theta))` .................2

sec(theta°) =
`(1)/(cos (72.542))` ..............3

sec(72.542°) =
`(1)/((0.3))`

sec(72.542°) = 3.333
