For each diagram below, solve for $x$ . Show all work.

Hint (a):
What trigonometric ratio can you use to find the value of $x$ ?
Answer (a):
$x = 8.17$

Hint (b):
Use the Law of Sines to find x.
Answer (b):
$\frac{ \text{sin}(102^{\circ}) }{7 }= \frac{ \text{sin}(62^{\circ}) }{x }$
$\sin102^\circ(x)=7(\sin62^\circ)$
$x=6.32$

Hint (c):
What trigonometric ratio can you use to find $x$ ?
