Given that angles 1 and 2 are vertical angles, they are equal in measure. Therefore, we can set up the equation:
\[ m\angle 1 = m\angle 2 \]
Substituting the given measures:
\[ 2x - 16 = 98 \]
To solve for \(x\), you can rearrange the equation.
Start by adding 16 to both sides:
\[ 2x - 16 + 16 = 98 + 16 \]
This simplifies to:
\[ 2x = 114 \]
Now, divide both sides by 2:
\[ x = 57 \]
The original equation set up can be expressed in the format you requested:
\[ 2x - 16 = 98 \]
So, in your format, it can be written as:
2 x - 16 = 98
This matches the structure you provided where the blanks represent coefficients and constants in the equation.
