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.

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.

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.

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°

No

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)

Step-by-step explanation:

Weight of rice in drum = 43 - 14 = 29kg

Option D is the correct answer

Step-by-step explanation:

step 1. 10t + 15 - 3t < 16 (distributive property)

step 2. 7t +15 < 16 (combine like terms)

step 3. 7t < 1 (subtract 15 from both sides)

step 4. t < 1/7 ( divide both sides by 7.

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]

9514 1404 393

Answer:

Step-by-step explanation:

The slope is the ratio of "rise" to "run". The "rise" is the vertical distance between two points; the "run" is the corresponding horizontal distance.

Here, we see point A is (0, 3) and point B is (1, 2). Then the "rise" is 2 -3 = -1, while the "run" is 1 - 0 = 1. The slope is the ratio ...

  m = rise/run = -1/1 = -1

The slope of the line is -1.

__

The point A is the y-intercept, where the line crosses the y-axis. It tells us the value of y is 3 when x=0. So, we can write the equation in slope-intercept form as ...

  y = mx + b . . . . . where m is the slope (-1) and b is the y-intercept (+3)

  y = -x +3

Step-by-step explanation:

Given,

Base of the triangle = 10

Hypotenuse of the triangle = 15

So, according to Pythagoras Theorem,

[tex] {c}^{2} - {a}^{2} = {b}^{2} [/tex]

[tex] {15}^{2} - {10}^{2} = {b}^{2} [/tex]

[tex]225 - 100 = {b}^{2} [/tex]

[tex]125 = {b}^{2} [/tex]

[tex]b = \sqrt{125} [/tex]

[tex]b = \sqrt{5 \times 5 \times 5} [/tex]

[tex]b = 5 \sqrt{5} cm \: (ans)[/tex]
