Answer: 2748.5 feet
Step-by-step explanation:
Given that the
Height h = 120 feet.
angle of depression = 2.5 degrees
The angle of depression is equal to the angle of elevation.
The base of the observation deck will be achieved by using trigonometry ratio.
Tan Ø = opposite/ adjacent
Opposite = height = 120 feet
Adjacent = base = ?
Substitutes the given parameters into the trigonometry ratio.
Tan 2.5 = 120 / adjacent
Adjacent = 120 / tan 2.5
Adjacent = 2748.452
Therefore, the base of the observation deck is 2748.5 feet
Answer:
52%
Step-by-step explanation:
62/120 * 100%
Divide by 2 on top and bottom
31/60 * 100 %
.5166666666 * 100 %
51.66666666 %
To the nearest whole number
Rounding the 1, we look at the 6 6>=5 so we round the 1 to 2
52%
Answer:
Kindly check attached picture
Step-by-step explanation:
Given the following :
First term (a) = 3
Second term = - 6
third term = 12
Fourth term = - 24
We can obtain the common ratio of the series using the relation :
(2nd term/ 1st term) = (3rd term/2nd term) = (4th term/ 3rd term) =....
(-6/3) = (12/-6) = (-24/12)
-2 = - 2 = - 2

13.7 is 100% I like to divide by 100 to get the 1%, then multiply by the percent i am trying to find, lets see if I'm right.
13.7/10 = .137
.137= 1/100
.137 x 160 = 21.92
Your answer is 21.92, 21.92 is 160%
Hope this helped!
To the nearest whole number would be 57, because .6 rounds up to the next whole number
