Answer: x=5.9

Explanation:

Use SOH CAH TOA to find full length then subtract to find x

full angle is 27+8=35

they gave adjacent and opposite to the angle so use TOA

tan 35 =
(y)/(31)

y=31 tan 35

y=21.71 this is the full length

now we do same for the shorter part lets call z

tan 27 =
(z)/(31)

z= 31 tan 27

z= 15.80 this is th bottom part of line

subtract to find x

x = y - z

x = 21.71 - 15.80

x=5.9
