First, it is important to understand that any equation that is x=some number is just a vertical line that hits the x-axis at the given number. For example, x=-2 would be a vertical line hitting the x-axis at -2. Therefore, the line we are trying to identify would also be vertical (and have the form x=some number) because we know the lines are parallel. Then, since we're given the point (-5,4), we know the line needs to hit the x-axis at -5, therefore the equation would be x=-5.
I hope this helps.

Answer: the altitude if the equilateral triangle is 5√2
Step-by-step explanation:
In an equilateral triangle, the 3 sides and the 3 angles are equal. The bisectors of each angle pass through the midpoint of the triangle. This means that each bisector divides the triangle into a two right angle triangles. The opposite side of the right angle triangle represents the altitude of the equilateral triangle. To find the altitude, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = adjacent side² + opposite side²
Opposite side = 8/2 = 4
Hypotenuse = 8
Therefore
8² = h² + 4²
h² = 64 - 14 = 50
h = √50 = √25 × √2
h = 5√2
