The picture in the attached figure
we know that
Applying the law of sines
b/sin B=a/sin A------> a=b*sin A/sin B
b=9
B=15°
A=180-(90+15)-----> A=75°
a=?
a=b*sin A/sin B-----> a=9*sin 75/sin 15----> a=33.59 units
the answer is33.59 units
It would be x=6 there’s the answer
How to get answer by Mimiwhatsup:

Answer:
55
Step-by-step explanation:
Because of the parallel lines (marked by those arrows) we know that the corner angles are the same:
110 - x = x so
110 = 2x
55 = x
