Since we don’t know the height of base or angles. We do know it is isosceles triangle.
x+4=3x-8
x-3x= -8-4
-2x= -12 multiply both sides by -1
2x=12
x=12/2
x=6
x+4=6+4=10
3x-8=3•6-8=18-8=10
Base equals x. x=10
AC=10

Answer:
The numbers are -21 and 21
Step-by-step explanation:
Let
x ----> one number
y ----> another number
S----> the sum of their squares
we know that
----> equation A
----> equation B
substitute equation A in equation B
This is the equation of a vertical parabola open upward
The vertex is a minimum
Find the coordinates of the vertex
Using a graphing tool
The vertex is the point (21,882) ----> see the attached figure
we have
x=21
<em>Find the value of y</em>
therefore
The numbers are -21 and 21
