Question

One quick math question in a screenshot below, thanks

Answer 1

sec(θ)=
`√(106) /9`

Explanation:

sec is hypotenuse over adjacent. So we need to find the value for the hypotenuse using the Pythagorean theorem. 9^2 + 5^2 =
`√(106)`. So sec of that angle would be the square root of 106 divided by 9 since 9 is the adjacent side to angle θ.
