Step-by-step explanation:
On day 14 he will have more then what he had to start with but you will need to Know how much he had.
It is not a triangle.
The two shortest side lengths add up to 42, which is the length of the longest side length. If this is true, the two shortest sides will just lay on top of the longest side and not form any interior angles or form a closed figure, thus there is no triangle formed.
Hope this helps!

______
Answer:
w is the width
L is the length
p is the perimeter
w=9
L=27
___________________
Step-by-step explanation:
p=2[(L-4) + (w+1)]
⇔p=2[(3w-4) + (w+1)]
⇔p=2[4w-3]
⇔p=8w-6
⇔66=8w-6
⇔8w=72
⇔w=9
Then L=3w=27

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,
Thus, the angle of elevation is 71.94 degrees.
