Answer:

m∠2 = 140°

Explanation:

m∠1 = m∠3, since they're vertical angles.

Solve for x:


2x+28=6x+4\\24=4x\\6=x

Plug in 6 for x for either m∠1 or m∠3. Doesn't matter since they're equal.

m∠1 = (2(6) + 28)°

m∠1 = (12 + 28)°

m∠1 = 40°

Now that we know m∠1, we can now solve for m∠2.

m∠1 + m∠2 = 180°

40° + m∠2 = 180°

m∠2 = 140°

By leveraging the supplementary relationship of angles 1 and 3, solving for x, and recognizing the vertical angles property, we determine that m(angle 2) is 56 degrees.

Angle 1 and angle 3 are supplementary angles. This means that together, they add up to 180 degrees. We can use this to write down an equation:

m(angle 1) + m(angle 3) = 180 degrees

We are given that m(angle 1) = (2x + 28) degrees and m(angle 3) = (6x + 4) degrees. Substituting these values into the equation, we get:

(2x + 28) degrees + (6x + 4) degrees = 180 degrees

Simplifying the equation, we get:

8x + 32 = 180 degrees

Subtracting 32 from both sides, we get:

8x = 148 degrees

Dividing both sides by 8, we get:

x = 18 degrees

Now that we know the value of x, we can find m(angle 2) using the fact that angle 1 and angle 2 are vertical angles. Vertical angles are angles that are opposite each other and have the same measure. Therefore, m(angle 2) = m(angle 1).

Substituting the value of x that we found earlier, we get:

m(angle 2) = 2 * 18 degrees + 28 degrees

Simplifying the equation, we get:

m(angle 2) = 56 degrees

Therefore, m(angle 2) = 56 degrees.
