State whether the following are true or false. Justify your answer.
$ \sec A=\frac{12}{5} $ for some value of angle $ A $.


Given:

Given statement is:

\( \sec A=\frac{12}{5} \) for some value of angle \( A \).

To do:

We have to state whether the given statement is true or false.

Solution:

$\sec\ A =\frac{Hypotenuse}{side\ adjacent\ to\ A}$

$=\frac{AC}{AB}$


In a triangle ABC, $AC$(Hypotenuse) is greater than $AB$.

Therefore,

$\frac{AC}{AB}$ is greater than 1.

This implies \( \sec A=\frac{12}{5} \) for some value of angle \( A \).

The given statement is true.
