50 is not a perfect square because it does not have a perfect square root where as 49 is 7, 121 is 11, and 1 is 1
The horizontal distance until the plan flies over the island is 2687.05 feet approximately.
<u>Solution:</u>
Given that, A plane at an altitude of 7000 ft is flying in the direction of an island
An angle of depression is 21 degree from the plane to the island
We have to find what is the horizontal distance until the plan flies over the island
The diagram is attached below
Assume as shown in the diagram
, now we can use the right angle triangle property




Hence, the distance between plane and point above island is 2687.05 feet approximately.
Answer:
the next two terms are 17, 20
Step-by-step explanation:
add 3 to each term
Example
5+3 = 8
8+3= 11
11+3= 14 etc.
Answer: 19.6 feet
Step-by-step explanation:
Using the Pythagorean theorem,

Well, given that a quarter equals 5 nickels, we can reason that, in order to get 12 coins, we would have to get 10 nickels (equals 50 cents) and 2 quarters (the other 50 cents, to make a dollar).
You didn't say whether you needed this expressed in a mathematical formula, but knowing the answer already, it shouldn't be hard to come up with one if necessary.
Hope this helps.
