Understanding Vertical Angles

In geometry, vertical angles are two angles that are opposite each other and share the same vertex. This means that they have the same measure and are equal in size. When dealing with vertical angles, we can use this property to solve for unknown values.

The Problem

We are given a figure with two vertical angles, $\angle 1$ and $\angle 2$ , with measures $m \angle 1=(2x-16)^{\circ}$ and $m \angle 2=98^{\circ}$ . Since vertical angles are equal, we can set up an equation to solve for $x$ .

Setting Up the Equation

Since vertical angles are equal, we can set up the following equation:

$(2x - 16) = 98$

This equation states that the measure of $\angle 1$ is equal to the measure of $\angle 2$ , which is $98^{\circ}$ .

Solving for x

To solve for $x$ , we need to isolate the variable $x$ on one side of the equation. We can do this by adding $16$ to both sides of the equation:

$2x - 16 + 16 = 98 + 16$

This simplifies to:

$2x = 114$

Next, we can divide both sides of the equation by $2$ to solve for $x$ :

$\frac{2x}{2} = \frac{114}{2}$

This simplifies to:

$x = 57$

Conclusion

In this article, we used the property of vertical angles to set up an equation and solve for $x$ . We started with a figure with two vertical angles, $\angle 1$ and $\angle 2$ , with measures $m \angle 1=(2x-16)^{\circ}$ and $m \angle 2=98^{\circ}$ . Since vertical angles are equal, we set up the equation $(2x - 16) = 98$ and solved for $x$ by adding $16$ to both sides, then dividing both sides by $2$ . The final solution is $x = 57$ .
