# The sum of two vertically opposite angles is 166°. Find each of the angles

**Solution:**

Given, the sum of two vertically opposite angles is 166°.

We have to find each of the angles.

__Vertical angles__ theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.

Let the angle be x.

By the definition,

x + x = 166°

2x = 166°

x = 166°/2

x = 83°

Therefore, the value of each angle is 83°.
