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.
