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.
