Question

The equation sin (25 degree) equals StartFraction 9 Over c EndFraction can be used to find the length of Line segment A B.

Answer 1

Answer:

$AB = 21.3$

Step-by-step explanation:

Given

$\sin(25) = \frac{9}{c}$

See attachment

Required

Find AB

We have:

$\sin(25) = \frac{9}{c}$

Make c the subject

$c = \frac{9}{\sin(25)}$

$c = 21.3$

From the attached triangle;

$AB = c = 21.3$

Hence:

$AB = 21.3$
