I think the answer is 90 degrees because both triangles are 90, but you're only finding KN and KL which is on ONE triangle not both. SO there's a 90 degree angle on the top triangle. So I'd go with 90, but I could be wrong.

A pilot is traveling at a height of 30,000 feet above ground she looks down at a angle of depression of 6 and spots runway as measured along the ground how many miles away is she from the runway
Answers
Distance between runway and pilot position along the ground is 285430.9336 feet that is 53.9464 miles.
Solution:Given that
Height of position of pilot from the ground = 30000 feet
Angle of depression when he looks down at runway = 6o
Need to measure along the ground, distance between runway and pilot that is horizontal distance between runway and pilot.
Consider the figure attached below
D represents position of runway.
P represents position of pilot.
PG represents height of position of pilot from the ground that means PG = 30000 feet
PH is virtual horizontal line and HPD is angle of depression means ∠ HPD = 6 degree
AS DG and HP are horizontals, so DG is parallel to HP.
=> ∠ HPD =∠ PDG = 6 degree [ Alternate interior angle made by transversal PD of two parallel lines ]
We need to calculate DG
Consider right angles triangle PGD right angles at G
[tex]\text {As } \tan x=\frac{\text { Perpendicular }}{\text { Base }}[/tex]
[tex]\tan \angle \mathrm{PDG}=\frac{\mathrm{PG}}{\mathrm{GD}}[/tex]
[tex]\begin{array}{l}{=>\mathrm{GD}=\frac{\mathrm{PG}}{\tan \angle \mathrm{PDG}}} \\\\ {=>\mathrm{GD}=\frac{30000}{\tan 6^{\circ}}=285430.9336}\end{array}[/tex]
As one foot = 0.000189 miles
[tex]=>285430.9336 \text { feet }=285430.9336 \times 0.000189 \text { miles }=53.9464 \text { miles. }[/tex]
Hence distance between runway and pilot position along the ground is 285430.9336 feet that is 53.9464 miles.
Final answer:
To find the distance to the runway, we can use trigonometry and create a right triangle using the pilot's height and the angle of depression. Using the tangent function, we can solve for the distance. The pilot is approximately 58.47 miles away from the runway.
Explanation:
To find the distance to the runway, we can use trigonometry. The angle of depression of 6 degrees tells us that the runway is below the pilot's line of sight. We can create a right triangle with the pilot's height of 30,000 feet as the opposite side and the distance to the runway as the adjacent side. Using the tangent function, we can solve for the distance:
Tan(6) = Opposite/Adjacent
Tan(6) = 30,000/Adjacent
Adjacent = 30,000/Tan(6)
Using a calculator, we find that the pilot is approximately 308,517 feet away from the runway.
To convert this distance to miles, we divide by 5,280 (since there are 5,280 feet in a mile):
308,517/5,280 ≈ 58.47 miles
Therefore, the pilot is approximately 58.47 miles away from the runway.

Find the height of the image after it has been scaled by 80% the following number of times. Explain or show your reasoning
Answers
After 3 times, it reduces to 76.8 mm, and after 6 times, it further reduces to approximately 39.3 mm.
To find the height of the image after it has been scaled by 80% multiple times, we can use the formula for scaling:
[tex]\[ \text{New height} = \text{Original height} \times (\text{Scale factor})^{\text{Number of times scaled}} \][/tex]
Given that the original height is 150 mm and the scale factor is 80% (or 0.8), we can calculate:
a. After being scaled 3 times:
[tex]\[ \text{New height} = 150 \times (0.8)^3 = 150 \times 0.512 = 76.8 \, \text{mm} \][/tex]
b. After being scaled 6 times:
[tex]\[ \text{New height} = 150 \times (0.8)^6 = 150 \times 0.262 \approx 39.3 \, \text{mm} \][/tex]
As the image is scaled down by 80% each time, its height decreases significantly with each iteration.
After 3 times, it reduces to 76.8 mm, and after 6 times, it further reduces to approximately 39.3 mm.
These heights fall within the acceptable range for a U.S. passport photo (25-35 mm).

5. An $800 deposit for 24
months earned $200 in
interest
Answers
Answer:
The rate of interest applied fro compound interest is 24.5 %
The rate of interest applied simple interest is 37.5 %
Step-by-step explanation:
Given as :
The Principal amount that is deposited = $ 800
The Time period = 24 months = 2 years
The Interest earn = $ 200
Let the rate of interest = R %
So, The Amount = Principal deposited - interest earn
Or, A = $ 800 - $ 200
∴ Amount = $ 600
From compounded method
Amount = Principal × [tex](1+\dfrac{\textrm rate}{100})^{\textrm Time}[/tex]
Or, $ 600 = $ 200 × [tex](1+\dfrac{\textrm R}{100})^{\textrm 2}[/tex]
Or, [tex]\frac{600}{200}[/tex] = [tex](1+\dfrac{\textrm R}{100})^{\textrm 2}[/tex]
Or, 3 = [tex](1+\dfrac{\textrm R}{100})^{\textrm 2}[/tex]
Or, [tex]3^{\frac{1}{2}}[/tex] = (1 +[tex]\frac{R}{100}[/tex])
Or, 1.245 = (1 +[tex]\frac{R}{100}[/tex])
or, 1.245 - 1 = [tex]\dfrac{R}{100}[/tex]
or, 0.245 × 100 = R
So, the rate is = 24.5 %
Hence The rate of interest applied fro compound interest is 24.5 % Answer
From Simple Interest method
Simple Interest = [tex]\dfrac{\textrm Principal\times \textrm Rate\times \textrm Time}{100}[/tex]
Or, $ 600 = [tex]\dfrac{\textrm 800\times \textrm R\times \textrm 2}{100}[/tex]
Or, $ 600 × 100 = $ 800 × R × 2
Or, R = [tex]\frac{60000}{1600}[/tex]
∴ R = 37.5 %
So, The rate is 37.5 %
Hence The rate of interest applied simple interest is 37.5 %Answer

Solve the equation x over 2 =6
Answers
Answer: 12
Step-by-step explanation: To solve this equation, since x is being divided by 2, in order to get x by itself, we need to multiply by 2 on both sides of the equation.
On the left side of the equation, the 2's cancel and we have x and on the right side of the equation, 6 × 2 gives us 12 so we have x = 12 which is the solution for our equation.
To check our solution, we plug 12 in for x in the original equation.

8 km + 2300 m +12,000 cm = ?
Answers
Answer:
The result is 10.42 kilometers, or 10,420 meters or 1'042,000 centimeters.
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
8 kilometers plus 2,300 meters plus 12,000 centimeters
2. Let's do the conversions to find the result either in kilometers, meters or even centimeters.
A. In kilometers:
8 kilometers
2,300 meters = 2.3 kilometers
12,000 centimeters = 120 meters = 0.12 kilometers
10.42 kilometers
B. In meters
8 kilometers = 8,000 meters
2,300 meters
12,000 centimeters = 120 meters
10,420 meters
C. In centimeters
8 kilometers = 8,000 meters = 800,000 centimeters
2,300 meters = 230,000 centimeters
12,000 centimeters
1'042,000 centimeters
The final sum is 10,420 meters.
To solve the mathematical problem of adding different units of measurement, we first need to convert everything to the same unit. In this case, let's convert all measurements to meters (m).
Convert 8 kilometers (km) to meters. Since 1 km = 1000 m => 8 km = 8 x 1000 => 8000 m.Convert 2300 meters (m) to meters. This is already in meters, so no conversion is needed and it remains 2300 m.Convert 12,000 centimeters (cm) to meters. Since 1 m = 100 cm, 12,000 cm = 12,000 / 100 = 120 m.Now, add these values together:
8000 m + 2300 m + 120 m = 10,420 meters

d. 50 + 10 + 5 yes no
Answers
Answer:
a. yes
b. no
c. yes
d. yes
Step-by-step explanation:
For a, 27 + 38 can be broken apart. 27 is broken up by adding smaller numbers (20 + 7 = 27) and the same is done with 38 (30 + 8 = 38), so A and C shows a way to add 27 and 38. In C, the numbers are just put into a different order. B is not a way to add 27 and 38, because the sum is different.
27 + 38 = 65, however 20 + 70 + 38 = 128. The addition problem for D is a way to solve for 27 + 38, because it is broken up differently than A and C. They instead added the 20 and 30 together first, then split up 15 (from 8+7) into 10 and 5. So D is a way to solve, because it gets the same answer as 27 and 38 :D
