To find the angle of elevation, we need to determine the height of the plane relative to the trees, and then use the tangent function to find the angle. Let's call the height of the plane "h".
We can set up a right triangle with the height of the plane, the distance from the runway to the trees, and the height of the trees.
We have:
h / (150 + 75) = 100 / h
Solving for h, we find that:
h = 125
So the height of the plane relative to the trees is 125 feet.
Now we can use the tangent function to find the angle:
tan(angle) = 100 / 125
angle = tan^-1(100 / 125)
angle = approximately 53.13 degrees
Rounding to the nearest hundredths, the angle of elevation that the pilot must take to avoid crashing into the trees is 53.13 degrees.
A student is walking to school and sees a mirror on the ground.
She stops a short distance from the mirror to practice her Geometry.
She knows her own height and the height of the school. She also knows the distance from the mirror to the school from previous Geometry activity. She would like to calculate the distance she is standing from the mirror.
The height of the school is 30 ft.
The distance from the school to the mirror is 50 ft.
The height of the student is 6.3 ft.
What is the distance d between the student and the mirror?
The distance d between the student and the mirror is given by the similar triangles are d = 10.5 feet
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the triangles be represented as ΔABC and ΔCDE
Now , they are similar triangles
The measure of AB = height of the school = 30 feet
The measure of BC = distance from the school to the mirror = 50 feet
And ,
The measure of DE = height of the student = 6.3 feet
The measure of CD = distance d between the student and the mirror
So , the corresponding sides of similar triangles are in the same ratio
On simplifying the equation , we get
BC / AB = CD / DE
And , 50 / 30 = d / 6.3
Multiply by 6.3 on both sides , we get
d = ( 5/3 ) x 6.3
d = 31.5 / 3
d = 10.5 feet
Hence , the distance d between the student and the mirror is 10.5 feet

select the statement which is true about the functions over the interval [1,2]
The true statement is (b) Function 2 has the lowest average rate
How to determine the true statementWe start by calculating the average rates of each function
The interval is given as [1, 2]
For Function 1
We have
f(1) = -3
f(2) = 3
The average rate is then calculated as
Average rate = [f(2) - f(1)]/[2 - 1]
Average rate = (3 + 3)/1
Average rate = 6
For Function 2
We have
f(1) = (1/4)^1 + 4 = 4.25
f(2) = (1/4)^2 + 4 = 4.0625
The average rate is then calculated as
Average rate = [f(2) - f(1)]/[2 - 1]
Average rate = (4.0625 - 4.25)/1
Average rate =-0.1875
For Function 2
We have
f(1) = -2
f(2) = 0
The average rate is then calculated as
Average rate = [f(2) - f(1)]/[2 - 1]
Average rate = (0 + 2)/1
Average rate = 2
The lowest average rate is -0.1875 for function 2

what is the that justen wins
The probability that Justen wins is 4/9.
Determine the probabilityThe probability that Justen wins is determined by the likelihood that the highest number rolled on the two dice is a 1, 2, 3, or 4. To find this probability, we can first calculate the probability that the highest number rolled is a 5 or 6, which is what would cause Gaberil to win.
The probability of rolling a 5 or 6 on one die is 2/6, or 1/3. The probability of rolling a 5 or 6 on both dice is (1/3) * (1/3) = 1/9.
However, we also need to account for the possibility that one die rolls a 5 or 6 and the other does not.
This can happen in two ways: either the first die rolls a 5 or 6 and the second does not, or the first die does not roll a 5 or 6 and the second does.
The probability of each of these scenarios is (1/3) * (2/3) = 2/9.
So the total probability of Gaberil winning is 1/9 + 2/9 + 2/9 = 5/9.
Since there are only two possible outcomes (either Gaberil wins or Justen wins), the probability of Justen winning is 1 - the probability of Gaberil winning. So the probability of Justen winning is 1 - 5/9 = 4/9.
Therefore, the probability that Justen wins is 4/9.

∠A and ∠B are vertical angles. If m∠A=(7x−18) ∘ and m∠B=(6x−8) ∘ , then find the measure of ∠A.
The measure of angle A is 52 degree.
What is the measure of angle A?Vertical angles are angles that are opposite of each other when two lines crosses, they are congruent.
Given that;
Angle A = ( 7x - 18 )∘Angle B = ( 6x - 8)∘Since vertical angles are congruent,
Angle A = Angle B
Plug in the given values
( 7x - 18 ) = ( 6x - 8)
Solve for x
7x - 18 = 6x - 8
7x - 6x = -8 + 18
x = -8 + 18
x = 10
Hence, angle A will be;
Angle A = 7x - 18
Plug in x = 10
Angle A = 7( 10 ) - 18
Angle A = 70 - 18
Angle A = 52°

Figure ABCD is a square. If AC+BD=56, what is the length of AX?
Figure ABCD is a square. If AC+BD=56, the length of AX is 28.
How did we get the value?Since ABCD is a square, all sides have the same length, let's call it "x".
We know that the sum of the diagonals of a square is equal to twice the length of a side, so AC + BD = 2x.
Therefore, 56 = 2x, and x = 28.
So the length of AX (or any side of the square) is 28 units

What is triangle ?
Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.
Let's call the two legs of the right triangle a and b, and the hypotenuse c. The hypotenuse is the side opposite the right angle, so in this case, we have c = 29. We also know that one of the acute angles is 71 degrees.
Using trigonometry, we can use the tangent function to find the length of the base:
tan(71) = a/b
We can solve for b by multiplying both sides by b:
b tan(71) = a
Now we can substitute c = 29 and solve for b:
b = c / tan(71)
b = 29 / tan(71)
b ≈ 8.71
