This line has an undefined slope. This means that there is only a rise not a run

The x values stay the same no matter the y value.

This means that the equation is:

x = 3

I need the answer to the image

Answer:

∠B = 156°

Step-by-step explanation:

A line intersects two parallel lines this means that their opposite angles are transversals specifically the angles, A and B. And transversal angles are congruent so I can make this claim below:

$∠A = ∠B \\ 8x +78 = 2x +144$

Solving for x:

$8x +78 = 2x +144 \\ 8x -2x +78 = 2x -2x +144 \\ 6x +78 -78 = 144 -78 \\ 6x = 66 \\ \frac{6x}{6} = \frac{66}{6} \\ x = 11$

Solving Angle B if x = 11.

$∠B = 2x +144 \\ ∠B = 2(11) +144 \\ ∠B = 22 +144 \\ ∠B = 166$
