x =

The answer of your question is: x = 5

Step-by-step explanation:

It's and isosceles triangle then ∠ A = ∠C

                            73 = 8y - 7

                            8y = 73 + 7

                            8y = 80

                            y = 80 / 8

                            y = 10

                   ∠  C = 8(10) -7

                   ∠  C = 73°

The sum of the internal angles in a triangle equals 180°

  ∠A + ∠B + ∠C = 180°

 73° + (6x + 4) + 73° = 180°                            Substitution

 6x + 4 = 180 - 73 - 73

 6x =34 - 4

 6x = 30

   x = 30 / 6

   x = 5

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
