A 36 foot ladder just reaches the top of the building in forms an angle of 4.72 with the wall of the building. How many feet tal
l is the building? Round your answer to the nearest foot and do not write the units
1 answer:
The height of the building is 3 feet
<h3>How to determine the value</h3>
From the information given, we have that;
- Angle of elevation = 4. 72 degrees
- hypotenuse side = 36 feet tall
- Building height is the opposite side
Using the sine identity:
sin θ = opposite/hypotenuse
Substitute the values
sin 4. 72 = x/ 36
cross multiply
x = sin 4. 72 × 36
x = 0. 0822 × 36
x = 3 feet
Thus, the height of the building is 3 feet

Step-by-step explanation:
8x+6y=10
6y=10-8x
y=(10-8x)/6
If you mean where m=17 then the answer is 3 because 17-5 is 12 and 12/4 is 3.
Answer: H- hot dogs
J- juice box
6h+4j=16.70
3h+4j=10.85
Elimination:
-6h-4j=-16.70
3h+4j=10.85
-3h=-5.85
H= 1.95
3(1.95)+4j=10.85
5.85+4j=10.85
4j=5
J=1.25
1.95 dollars for a hotdog and 1.25 dollars for a juice box
