What is the value of sec theta in the triangle below

olya-2409 [2.1K]

Answer:

The answer to your question is the third choice secФ = 41/40

Step-by-step explanation:

Data

Opposite side = 9

Adjacent side = 40

hypotenuse = 41

Process

To solve this problem use trigonometric functions. The secant is the trigonometric function that relates the hypotenuse and the adjacent side.

sec Ф = hypotenuse / adjacent side

hypotenuse = 41

adjacent side = 40

then,

secФ = 41/40
