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!!!

If cot theta= 4/3, find csc theta

Marrrta [24]

Answer: Option d.

Step-by-step explanation:

The trigonometric identity needed is:

$csc^2\theta=cot^2\theta+1$

Knowing that $cot\theta=\frac{4}{3}$ :

Substitute it into $csc^2\theta=cot^2\theta+1$ :

$csc^2\theta=(\frac{4}{3})^2+1$

Simplify the expression:

$csc^2\theta=(\frac{4}{3})^2+1\\\\csc^2\theta=\frac{16}{9}+1\\\\csc^2\theta=\frac{25}{9}$

Solve for $csc\theta$ . Apply square root at both sides of the expression:

$\sqrt{csc^2\theta}=\±\sqrt{\frac{25}{9}}$

$csc\theta=\frac{5}{3}$
