Question

Find sec 0

is my answer correct? if not what's the right answer ​

Answer 1

Option(1)

Explanation:

By applying secant rule in the given right triangle,

secθ =
`\frac{\text{Hypotenuse}}{\text{Adjacent side}}`

From the picture attached,

Opposite side of angle θ = 5 units

By applying Pythagoras theorem,

(Hypotenuse)² = (leg 1)² + (leg 2)²

= (10)² + 5²

= 125

Hypotenuse = √125

= 5√5

Now substitute these values in the expression of secθ,

secθ =
`(5√(5))/(5)`

secθ = √5

Option (1) is the correct option.
