## What are intersecting and also parallel lines?

**Intersecting lines** space straight currently that meet or crosses each various other at a particular point. The figure below shows the illustration that 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) ° space vertical angles, discover the value of x.

Solution

Vertical angles space equal, therefore;

(3x + 7)0 = 100 0

3x = 100 – 7

3x = 93

x = 310

Hence, the worth of x is 31 degrees.

**Applications of Vertical angle (h3)**

Vertical angle have many applications that we watch or experience in our everyday lives.
