If sec(theta) =25/24, find cot(theta) (Picture provided)
larisa [96]

Answer:

B

Step-by-step explanation:

By the definition,

\sec \theta=\dfrac{\text{hypotenuse}}{\text{adjacent leg}}.

If \sec \theta=\dfrac{25}{24}, we can consider right triangle with hypotenuse 25 un. and adjacent leg 24 un. By the Pythagorean theorem,

\text{hypotenuse}^2=\text{adjacent leg}^2+\text{opposite leg}^2,\\ \\\text{opposite leg}^2=25^2-24^2,\\ \\\text{opposite leg}^2=625-576,\\ \\\text{opposite leg}^2=49,\\ \\\text{opposite leg}=7\ un.

So,

\cot \theta=\dfrac{\text{adjacent leg}}{\text{opposite leg}}=\dfrac{24}{7}.
