$\sin (θ) = \frac{7}{25}$

Step 1

To find the value of $\csc (θ)$ , use the fact that $\frac{1}{\sin (θ)}$ then substitute in the known values.

$\csc (θ) = \frac{1}{\sin (θ)} = \frac{1}{\frac{7}{25}}$

Step 2

Simplify the result.

Step 2.1

Multiply the numerator by the reciprocal of the denominator.

$\csc (θ) = \frac{1}{\sin (θ)} = 1 (\frac{25}{7})$

Step 2.2

Multiply $\frac{25}{7}$ by $1$ .

$\csc (θ) = \frac{1}{\sin (θ)} = \frac{25}{7}$
