Corey spies a bald eagle in a tall tree. He estimates the height of the tree to be 60 feet and the angle of elevation to the bird from where he stands to be 64°. The leaves on the tree make it difficult for Corey to watch the bird, so he takes many steps away from the tree to get a better view. He now estimates his angle of elevation to be 37°.
How many feet did Corey step back to gain a better view of the bird? Round your answer to the nearest hundredth of a foot.
Answers
Answer:
Corey stepped back 59.71 feet
Step-by-step explanation:
Right Triangles
They are a special type of triangle where one of its internal angles is 90°. The basic trigonometric equations stand in this type of triangles. If x is the adjacent leg of a given angle , and y is the opposite leg to the same angle, then :
[tex]tan0= \frac{y}{x}[/tex]
We can solve for x to get
[tex]x = \frac{y}{tan0}[/tex]
Corey estimates the height of the tree to be 80 feet. This means we know y=80 and . Let's find the horizontal distance at which Corey is looking at the bald eagle:
[tex]x1 =\frac{80}{tan68}[/tex]
[tex]x1 = 32.32 feet[/tex]
Now Corey moves back to watch the very same tree at an elevation angle of 41°. The tree has the same height, so
[tex]x2 =\frac{80}{tan41}[/tex]
[tex]x2= 93.03 feet[/tex]
Now we can know the distance Corey walked back by subtracting both distances
correy stepped back 59.71 feet
The number of feets corey will step back to gain a better view of the bird is 54.72feet.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.
In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slant side is called hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.
here, we have,
Given that;
The height of tree=80feet
The angle of elevation to the bird from him=68°.
His estimated angle of elevation = 41°
Now,
Use trig to find x
then use trig to find x+y
Then subtract to find y
tan41°= 80ft/(80ft/tan65 + y)
80/tan65 + y = 80/tan41
y= 80/tan41 - 80/tan65
y= 54.72ft
Therefore, by trigonometry the answer will be 54.72feet.

Find the equation of the line that is perpendicular to the x-axis and passes through the point (-10,-1). Give the full equation as your answer. The equation is _______________
Answers
Answer:
x = -10
Step-by-step explanation:
First, determine the slope of the answer. The x-axis is a horizontal line, thus the new line must be vertical. All vertical lines are represented by the equation x = a number. That number represents the x-value of all the points the vertical line passes through.
So, since the line passes through (-10, -1), take the x-value of that point and put it into that equation. Thus, x = -10.

Topic: Explain all the steps taken to solve the problem below. The measure of the interior angles of the polygon ABCDE are shown below. Determine the measure of angle E.
Answers
9514 1404 393
Answer:
∠E = 156°
Step-by-step explanation:
The sum of angle measures in a pentagon is 540°, so we have ...
95 +(7x -4) +90 +(9x -6) +(3x +23) = 540
19x +198 = 540
19x = 342 . . . . . . . subtract 198
x = 18 . . . . . . . . . . .divide by 19
Then the measure of angle E is ...
∠E = (9x -6)° = (9·18 -6)°
∠E = 156°
Find the equation of a line, in slope-intercept form of a line that passes through the point (-5, -1) and is parallel to -2x+4y=8.
Answers
Answer:
[tex]y=\frac{1}{2}x+\frac{3}{2}[/tex]
Step-by-step explanation:
Let's write [tex]-2x+4y=8[/tex] to slope-intercept form.
We do this by solving for [tex]y[/tex]
[tex]-2x+4y=8\\[/tex]
Add 2x to both sides
[tex]4y=8+2x[/tex]
Divide both sides by 4
[tex]y=\frac{1}{2} x+2[/tex]
Now that we have that equation in slope-intercept form, the question wants us to find a line that is parallel to it that passes the point (-5, -1).
A line is parallel to another line is they have the same exact slope.
The slope is [tex]\frac{1}{2}[/tex].
Slope-intercept form: [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
So, let's see what we have here so far.
[tex]y=\frac{1}{2}x +b[/tex]
All we have to do is find [tex]b[/tex].
The question wants the line to pass the point (-5, -1).
Let's plug that point in.
[tex]-1=\frac{1}{2} (-5)+b\\-1=\frac{-5}{2}+b\\\frac{3}{2} =b\\[/tex]
We have all the information needed to finish this problem!
So, the line that is parallel to [tex]-2x+4y=8[/tex] and passes through the point (-5, -1).
[tex]y=\frac{1}{2}x+\frac{3}{2}[/tex]

C: 3t ( 18s - 7)
D: 7s ( 8t - 3t)
Answers
Answer:
B: 7t(8s - 3)
Step-by-step explanation:
Method 1: check by expanding each of them
A: 7(8st - 3t)=56st-21t
B: 7t(8s - 3)=56st-2t
C: 3t ( 18s - 7)=54st-21t
D: 7s ( 8t - 3t)=56st-21st
Method 2: the common factors of 56st and 21t is: 7t
56st/7t=8s
-21t/7t=-3
56st-21t=7t(8s-3)
