∠1 and angle, 2∠2 are vertical angles. If mangle, 1, equals, left parenthesis, 2, x, plus, 16, right parenthesis, degrees∠1=(2x+16)


and mangle, 2, equals, left parenthesis, 6, x, minus, 8, right parenthesis, degrees∠2=(6x−8)

1 answer

Since angles \( \angle 1 \) and \( \angle 2 \) are vertical angles, they are equal in measure. Therefore, we can set up the equation:

\[ 2x + 16 = 6x - 8 \]

To solve for \( x \), we first isolate the terms involving \( x \) on one side of the equation. We can start by subtracting \( 2x \) from both sides:

\[ 16 = 6x - 2x - 8 \]

This simplifies to:

\[ 16 = 4x - 8 \]

Next, we add \( 8 \) to both sides:

\[ 16 + 8 = 4x \]

So we have:

\[ 24 = 4x \]

Now, we divide both sides by \( 4 \):

\[ x = 6 \]

Now that we have \( x \), we can find the measure of \( \angle 2 \) using the expression for \( \angle 2 \):

\[ \angle 2 = 6x - 8 \]

Substituting \( x = 6 \):

\[ \angle 2 = 6(6) - 8 \]

Calculating this gives:

\[ \angle 2 = 36 - 8 = 28 \]

Thus, the measure of \( \angle 2 \) is:

\[ \boxed{28} \text{ degrees} \]
