Answer: The angle of elevation should be 38.9 degrees.
To find this answer, it is always best to draw a picture of the building. The point of the roof, will be directly over the middle of the cabin. Therefore, we could draw an altitude down from the top to the cabin and create a right triangle.
This would form a triangle with an adjacent side and hypotenuse with our needed angle.
We could write and solve the following cosine equation:
cos(x) = 21/27
x = 38.9
Answer:
231
Step-by-step explanation:
Since prime numbers are always relatively prime, we can just multiply them together. 3*7*11=21*11=231
Answer:
No
Step-by-step explanation:
To be divisible by 4 the last two digits have to be divisible by 4
so

no
because is odd and four is even
so we can conclude that 563 is not divisible by 4
