<h3>Given Equation:</h3>
6 - 2n = -4n - 2 - 8
<h3>To Find:</h3>
The value of n.
<h3>Solution:</h3>
6 - 2n = -4n - 2 - 8
or, -2n + 4n = -2 - 8 - 6
or, 2n = -16
or, n = -16/2
or, n = -8
<h2>Answer:</h2>
The value of n is -8.
The geometry technique that Chee uses to find the height of the goalpost is the equal ratio of the corresponding sides of similar triangles.
Correct response:
- The eight of the goalpost is approximately <u>16.91 meters</u>.
<h3>Methods used to calculate the height</h3>
The length Chee is using the mirror to measure = The height of her school's football goalpost
The distance of the mirror from the goalpost = 14.35 meters
The distance on the other side of the mirror Chee steps to = 1.4 meters
The distance from her eyes to the ground = 1.65 meters
Required:
How tall is the goalpost.
Solution:
By using similar triangles relationships, we have;

Which gives;

- The height of the goalpost, h ≈ <u>16.91 meters</u>
