Step-by-step explanation:
Is because when you have two negative -- signs it became positive
19 + 41 = 60
The closer Diana gets to the building, the smaller the angle becomes
Diana is 17.6 feet closer to the building
<h3>How to calculate the distance from the building</h3>
To calculate the distance between her and the building, we make use of the following tangent ratio
Where:
- h represents the height of the building; h = 130
- d represents the distance from the building
So, we have:
Make d the subject
Evaluate tan(40)
Initially, Diana is at a distance of 172.53.
The difference in both distance is:
Hence, Diana is 17.6 feet closer to the building
