Answer:
The angle of elevation from the person is ~ 19.7 feet
Step-by-step explanation:
Call the distance from the person to the tree is A and the bird's nest to the ground is B (right angle side of right triangle)
The distance from the person to the bird's nest is the hypotenuse (call C) of the right triangle
To find the hypotenuse we take the square root of the sum of the squares of the two sides of the right angle.

Answer:
X =1/39
Step-by-step explanation:
1/2+ 6X = 5/6 - 7X Transposing terms
6X + 7X =5/6 - 1/2
13X = 5/6 - 3/6
13X = 2/6 simplifying
13X = 1/3
and transposing 13:
X =1 / (13x3) reducing
X= 1/39
84 can’t be a perfect square
y= -947/8
Just isolate the variables, even though this is a long, painstaking, agonizing process

Answer:
B
Step-by-step explanation:
Given
y² - 12y + 32
Consider the factors of the constant term (+ 32) which sum to give the coefficient of the y- term (- 12)
The factors are - 4 and - 8, since
- 4 × - 8 = 32 and - 4 - 8 = - 12, thus
y² - 12y + 32 = (y - 4)(y - 8) → B
