Question

Given secant of theta is equal to the square root of 10 over 2 comma what is cos?

Answer 1

Answer:

D square root of 10 over 5

Step-by-step explanation:

sec means $\frac{1}{x}$, so if sec of theta is $\frac{\sqrt{10} }{2}$ in this situation then you can set those equal to one another to get x.

x=$\frac{\sqrt{10} }{5}$

cos is just another way to say x so what you got for x is your answer

Answer 2

The secant of theta is equal to the square root of 10 over 2 comma what is, then the value of cos is square root of 10 over 5 .The correct option is d.

What is secant?

For a right angle triangle, secant of the angle formed by the sides opposite to hypotenuse is equal to the ratio of Hypotenuse and the base of triangle,

Given the value of sec of θ

secθ = sqrt (10)/2

Then cos θ = 1/secθ

Plug the value, we get

secθ=  sqrt  (10) / 5

Thus, the correct option is d.
