Answer:
The angle of elevation of the sun from the ground to the top of a tree is
.
Step-by-step explanation:
As given
The sun from the ground to the top of a tree when a tree that is 10 yards tall casts a shadow 14 yards long.
Now by using the trignometric identity .

As figure is given below .
AB = Perpendicular = 10 yards
BC = Base = 14 yards
Putting all the values in the trignometric identity .




Therefore the angle of elevation of the sun from the ground to the top of a tree is
.
You are adding 6 to each number. (N-1)+6, I guess
Answer:
It is the second answer.
Step-by-step explanation:
When numbers with the same base are multiplied, you add the bases.
1/2 + 3/4 is the same as
2/4 + 3/4 = 5/4
So now we have 2 ^5/4^2. When we have a power raised to a power. We multiply the powers.
5/4(2)
(5/4(2/1) = 10/4 = 5/2. The second answer is the same way to describe
2^(5/2)
Answer:

Step-by-step explanation:
1) Use square sum: (a + b)² = a² + 2ab + b².
