X/5 = 8/9
this is a proportion, so we cross multiply
(9)(x) = (5)(8)
9x = 40
x = 40/9 or 4 4/9

Answer:
F altitude
Step-by-step explanation:
AB is perpendicular to triangle base XZ, so is an altitude of the triangle.
__
<em>Additional comment</em>
B is not the midpoint of XZ, so AB is not the median and not a bisector of XZ. Likewise, AB is not the angle bisector of angle A. (The triangle would have to be isosceles for AB to be a perpendicular bisector, median, and angle bisector.)
Eliminating the choices that can't work leaves the one that does work. AB is the altitude.
Given:
Consider the given equation is:

To find:
The slope of the line that is represented by the given equation.
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope and b is y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get

Therefore, the slope of the given equation is
.
Step-by-step explanation:
The answer is the third option
Are you sure it’s a scalene triangle because if you only know one side and all the other sides are different lengths then it’s impossible to computer unless we know angle measures. It would have to be isoceles or we would need angle measures
