Answer:
<u>135.94 feet</u>
Step-by-step explanation:
Split the problem into two parts :
- Distance between viewer and building
- Height of the top part of the building
<u>Distance between viewer and building</u>
- The lower part of the building is 40 feet, as it is mentioned the viewer is 40 feet above street level
- Let the distance be called 'd'
- Therefore, tan37° = 40/d
- tan37° = 3/4 = 0.75
- ⇒ 40/d = 0.75
- ⇒ d = 40/(3/4) = 40 x 4/3 = 160/3 = 53.3 feet
<u>Height of the top part of the building</u>
- Let the height of the top part be 'h'
- Therefore, tan61° = h/d = h/53.3
- tan61° = 1.8
- ⇒ h/53.3 = 1.8
- ⇒ h = 53.3 x 1.8 = 95.94 feet
<u>Total height of building</u>
- Lower part + Top part
- 40 + 95.94
- <u>135.94 feet</u>

The correct answer is x=4
Hello!
A period of a function like the sin graph or cosine graph are periodic because they repeat themselves on a interval and never end and each interval from trough to trough or peak to peak is called one period. Or another way if looking at it is one period is the time for one complete cycle of motion before it repeats itself.
Hope this helps thanks.
Answer : 35 brownies
==================================
working:
3/5 = 21
1/5 = 21 / 3
1/5 = 7
5/5 = 7 x 5
1 (the amount of brownies she brought) = 35
Therefore, she brought 35 brownies
