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>

Answer:
11.1%
Step-by-step explanation:
The percentage change in a value can be computed from ...
%change = ((new value)/(old value) -1) × 100%
= ((8500/9559) -1) × 100%
= (0.8892 -1) × 100%
= -11.08%
The value of the car decreased about 11.1% in the first year.
