Answer:

The sum of the two interior angles of the triangle are equal to the exterior angle.

So we set up the equation;

(3x + 8) + x = 6x - 32

Combine like terms:

4x + 8 = 6x - 32

Let's get rid of the constants on the right side by adding 32 to both sides (because we're applying inverse operations)

+32 +32

4x + 40 = 6x

Now let's group the coefficients that have x, by subtracting 4x from both sides;

-4x -4x

40 = 2x

Divide by 2 so we can isolate x;

/2 /2

20° = x
