The distance between the points A to B is 899.9 feet. After rounding off the nearest integer we get 900 feet as the final answer.
Given we know that CD is perpendicular to AD.
The distance between CD is 139 feet.
As from points A the boat's crew measure the angle of elevation to the beacon as 6°
therefore, m∠A = 6°
Another time the angle of elevation is measured from point B which is 19°.
therefore, m∠DBC = 19°
tan 19° = CD/BD
BD = CD/tan19°
BD = 136/tan 19°
now for tan 6° = CD/AD (tangent is opposite over adjacent)
AD = CD/tan 6°
AD = 136/tan 6°
AB = AD ₋ BD
AB = 136/tan 6° ₋ 136/tan 19°
AB = 1295.2 ₋ 395.3
AB = 900 feet
hence the distance from point A to B is 900 feet.

Answer:
sure
Step-by-step explanation:
One meter is 3.28 feet, so anything shorter than that. A basketball, maybe a very young child?
The definition of a prime number is one in which there are no factors other than 1 and itself. For example, 5 has no other factors other than 1 and 5 (itself).
The number 1 is not considered prime nor composite.So, even though it is a square (1²), it is not a prime number.
All square numbers have a square root that is neither 1 nor itself: 16 is the square of 4, 49 the square of 7, and so on.
Due to the fact that square numbers have factors other than 1 and itself, square numbers are not prime.
Hope this helps! :)
The missing expression should be for Step 3 is [(25 + 3)/0.5] - 16.4 ÷ 4 and the missing expression should be for Step 6 is 56 - 4.1
<h3>Part A: Explain what the missing expression should be for Step 3</h3>
To do this, we make use of the expression in step 2
The expression in step 2 is
[(5^2 + 3)/0.5] - 16.4 ÷ 4
The next step at this stage is to evaluate the expression 5^2
So, we have:
[(25 + 3)/0.5] - 16.4 ÷ 4
Hence, the missing expression should be for Step 3 is [(25 + 3)/0.5] - 16.4 ÷ 4
<h3>Part B: Explain what the missing expression should be for Step 6.</h3>
To do this, we make use of the expression in step 5
The expression in step 5 is
56 - 16.4 ÷ 4
The next step at this stage is to evaluate the expression 16.4 ÷ 4
So, we have:
56 - 4.1
Hence, the missing expression should be for Step 6 is 56 - 4.1
