Answer:
4 meters
Step-by-step explanation:
Given that :
Initial elevation of butterfly = 20 meter
Change in elevation from initial height = negative 16 m = - 16 meter
Final elevation can be obtained by taking the sum of initial elevation and the change in elevation
(20 m + (- 16 m))
(20 m - 16 m)
= 4 meters
1/6 + 5\6
2/6 + 4\6
3/6 + 3/6
Answer:
The angle of elevation is 71.94 degrees.
Step-by-step explanation:
We are given the following in the question:
The front of an A-frame cottage has the shape of an isosceles triangle.
Height,h = 23 feet
Base,b = 15 feet
We have to find the angle of elevation of its roof.
The attached image shows the structure.
We use the relation,
![\tan \theta = \dfrac{h}{\frac{b}{2}}\\\\\tan \theta = \dfrac{23}{7.5}\\\\\tan \theta = 3.067\\\theta = \tan^{-1}3.067 = 71.94^\circ](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3D%20%5Cdfrac%7Bh%7D%7B%5Cfrac%7Bb%7D%7B2%7D%7D%5C%5C%5C%5C%5Ctan%20%5Ctheta%20%3D%20%5Cdfrac%7B23%7D%7B7.5%7D%5C%5C%5C%5C%5Ctan%20%5Ctheta%20%3D%203.067%5C%5C%5Ctheta%20%3D%20%5Ctan%5E%7B-1%7D3.067%20%3D%2071.94%5E%5Ccirc)
Thus, the angle of elevation is 71.94 degrees.
To get the result we have to divide number of cups by number of children.
5:8=0.625
0.625 means that each children can get less than 1 cup of juice.
