Find the value of x in the triangle shown below

CaHeK987 [17]

Answer:

Step-by-step explanation:

Apply sine formula:

$\frac{sin \: a}{a} = \frac{sin \: b}{b} = \frac{sin \: c}{c}$

$\frac{sin \: a}{a} = \frac{sin \: c}{c}$

Plug the values

$\frac{sin \: (88)}{6.9} = \frac{sin \: x}{5}$

Apply cross product property

$5 \: sin \: (88) = 6.9 \: (sin \: x)$

$\frac{5 \: sin \: (88)}{6.9} = sin \: x$

$x = {sin}^{ - 1} ( \frac{5 \: sin \:( 88)}{6.9} )$

$x = 46.4$

Hope this helps .....

Best regards!!!
