In this article, we room going to discover **what vertical angle are** and also **how to calculation them**. Prior to we begin, let’s very first familiarize ourselves with the following concepts around lines.

## What room intersecting and parallel lines?

**Intersecting lines** are straight lines that meet or the cross each various other at a certain point. The figure listed below shows the illustration of intersecting lines.

Solution

1400 + z = 1800

z = 1800 – 1400

z = 400

But (x + y) + z = 1800

(x + y) + 400 = 1800

x + y = 1400

900 + y = 1400

y = 500

*Example 4*

If 1000 and also (3x + 7) ° room vertical angles, find the worth of x.

Solution

Vertical angles room equal, therefore;

(3x + 7)0 = 100 0

3x = 100 – 7

3x = 93

x = 310

Hence, the value of x is 31 degrees.

**Applications the Vertical angles (h3)**

Vertical angle have numerous applications that we check out or endure in our day-to-day lives.
