A teacher is flying a drone as shown in the diagram below. The drone is maintaining a height of approximately 150 feet above his eye level. What is the approximate angle of elevation from his eye level to the drone when the drone is approximately 200 feet away from him?​

Step-by-step explanation:

2x+80=180

2x=100

x=50

hope this helps

Answer:

Step-by-step explanation:

Adjacent interior angles of a parallelogram are supplementary

Let the small angle is x, the other angle is:

The sum of two angles is 180°

The angles are 50°, 50°, 130°, 130°

Sum of interior angles of a pentagon is:

Two of the angles are supplementary, so they sum to 180°

The sum of the remaining 3 angles is:

Each of the congruent angles is 120°

Answer: 37.5%

Step-by-step explanation:

Percentage = Given Quantity/Total Quantity*100

So here, it will be like: 45/120*100

                                    =0.375*100

                                    =37.5%

Answer:

width=x

length =2x.....

Answer:

l = 2w

Step-by-step explanation:

note:

l = lenght

w = width

so lenght  is 2 times width is -

l = 2w

the dash is the fraction symbol

Answer:

Look below

Step-by-step explanation:

9 would be a solution of the inequality x>5 because x can represent any number, but because there is a > between x and 5, that means that whatever number x represents is greater than 5, and because 9 is greater than 5, it is a solution to the inequality.

Hope this helps :)

Try looking, how many words can she find in 1 minute, then try to calculate how you got that into 5! It's easy if you think about it!

good luck!

Answer:

37

Step-by-step explanation:

10x40 = 400

2(39+42)+ 40 x 4 + 41 + X = 400

162 + 160 + 41 = 400 - X

400 - 363 = X

X= 37

Answer:

C. In y^2-y=6, 6 should have been subtracted on both sides first.

Step-by-step explanation:

It is a quadratic equation so you subtract the 6 and create

y^2-y-6=0

Then you factor it to:

(y-3)(y+2)=0

The solutions then are:

y-3=0, y=3 and y+2=0, y=-2

{-2,3}

Answer:

The answer is C. Which is 248 square inches.

1.) 12m = d

2.) 120

Answer:

d=12m

$120

Explained

part 1:

d=12m (dollars = $12 times the m (the number of mows))

part 2:

m=10

d=12 (10)

d=$120

Answer:

x=-1/5

y=41/5

I am not able to explain to you how I achieved these results, but at least you can try and see if you can solve the equation.

Answer:

No, (2,6) is not a solution to this system of equations.

Explanation:

Okay so lets restate the question:

Is (2, 6) a solution to this system of equations?

y = x + 4

y = 9x + 10

First, you find the x and y intercepts from the equations stated above.

y=x+4

x intercept(s): (-4,0)

y intercept(s): (0,4)

So for the first equation, (2,6) is not a solution.

Now, we find the x and y intercepts for the second equation.

y=9x+10

x intercept(s): (-10/9,0)

y intercept(s): (0,10)

So for the second equation, (2,6) is not a solution.

Both equations do not have (2,6) involved.

And its 24 points not 48 :((((

Answer:

Answer: 0 is smallest perfect square but if Any number that can be written as a POSITIVE integer to the power of 2. then 1 is the smallest perfect square number.

Answer:

Answer: 0 is smallest perfect square but if Any number that can be written as a POSITIVE integer to the power of 2. then 1 is the smallest perfect square number.

Step-by-step explanation:

Answer: Since this is the right triangle so

[tex]Sin B = \frac{AC}{AB} =\frac{AC}{6} \\=> AC = sin(20) * 6 = 5.478 = 5.48[/tex]

Apply Pythagorean theorem:

[tex]AC^{2} +CB^{2} =AB^{2} \\5.48^{2} +CB^{2} =6^{2}[/tex]

[tex]CB = \sqrt{6^{2} -5.48^{2} } = 2.44[/tex]

Answer:

Ann has 24 $1 bills, 2 $10 bills, and 8 $20 bills.

Step-by-step explanation:

Given that Ann has $1, $10, and $20 bills, and she has 4 times as many $20 bills as $10 bills and 3 times as many $1 bills as $20 bills, taking a total of $204, to determine the number of $1, $10, and $20 bills she has, she needs to perform the following calculation:

1 = 3x20 = 3x4x10 = 12x10

20 = 4x10

10 = 10

(12 x 1) + (4 x 20) + 10 = 12 + 80 + 10 = 102

(24 x 1) + (8 x 20) + (2 x 10) = 24 + 160 + 20 = 204

So Ann has 24 $1 bills, 2 $10 bills, and 8 $20 bills.

Answer:

3

Step-by-step explanation:

We can find the slope of the given line in this two way:

1) the faster is calculate -a/b where a is the number the multiply x and b is the number the multiply y. In this case we have -1/3

2) the second method is rewrite the equation in slope intercept form and find the therm that multiply x

3y = -x-15

y = -1/3x - 5

Also in this case we have -1/3

Two perpendicular lines have the the product of the their slope that is -1

So the slope that we are finding is 3

In fact = 3 x -1/3 = -1
