Question

The equation sin(25") = 9/c

Answer 1

Option B: 21.3 in is the length of AB

Explanation:

The equation is $\sin 25^{\circ}=\frac{9}{c}$

To find the length of AB, let us equate,

$c=\frac{9}{\sin 25^{\circ}}$

Substituting the value for sin 25°, we get,

$c=\frac{9}{0.4226}}$

Dividing the values, we have

$c=21.3$

Thus, the length of AB is 21.3 in.

The correct answer is Option B.
