Since the triangle is isosceles we know that angle a is equal to angle c.
8y-7=73
8y=80
y=10
We also know that the sum of the interior angles in any triangle is 180 degrees.
73+73+6x+4=180
150+6x=180
6x=30
x=5
The answer to your question should be B.
Your constant is 3 because it’s alone
1 4 8 2
im pretty sure thats right hope that helps
