Answer:

The remaining side has a length of six units.

Step-by-step explanation:

We know that this is an Isosceles triangle because angles A and C are marked as being the same angle. So we know that AB and CB are the same length.

As we're given their lengths, we can simply equate the two, and solve for x:

$x + 4 = 3x - 8\\12 = 2x\\x = 6$

So we know that the remaining side has a length of 6.

Without simplifying, identify the slope of the line given by the equation y-5=-2(x+5)

CaHeK987 [17]

Slope is a number in front of x, so slope is (-2)

y-y1=m(x-x1)
y-5= -2(x+5)
y-5= -2(x-(-5))
so y1=5, x1=-5, a point is (x1,y1), so the point is (-5,5)
