Answer:

$x = 9.2$

$x =22.0$

$x = 8.7$

Step-by-step explanation:

Required

Find x

(a)

x is calculated using tangent formula

$\tan(57) = \frac{x}{6}$

Make x the subject

$x = 6 * \tan(57)$

$x = 6 * 1.5399$

$x = 9.2394$

$x = 9.2$ --- approximated

(b):

x is calculated using cosine formula

$\cos(60) = \frac{11}{x}$

Make x the subject

$x = \frac{11}{\cos(60)}$

$x = \frac{11}{0.5}$

$x =22.0$

(c):

x is calculated using sine formula

$\sin(60) = \frac{x}{10}$

Make x the subject

$x = 10 * \sin(60)$

$x = 10 * 0.8660$

$x = 8.660$

$x = 8.7$ --- approximated
