<h2>In the attachment</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
(x₁, y₁) - point
We have the equation:

Therefore we have
the slope m = -2/3
and the point (-9, 5)
A slope

rise = -2
run = 3
From the point (-9, 5) ⇒ 2 units down and 3 units to the right.

As we know, sum of interior angles of a triangle is 180°
that is ~
Hence, value of x is 9°
