Answer:
The correct option is 1.
Step-by-step explanation:
The angle of elevation is the angle formed by the line of sight and the horizontal plane for an object above the horizontal.
The angle of depression is the angle formed by the line of sight and the horizontal plane for an object below the horizontal.
Since the angle 4 is the angle between the line of sight and the ground for an object above the horizontal, therefore angle 4 is the angle of elevation from the person to the radar tower.
1. "Angle 4 is the angle of elevation from the person to the radar tower."
This statement is true.
2. "Angle 4 is the angle of depression from the radar tower to the person".
This statement is is false.
3. "Angle 4 is the angle of depression from the person to the radar tower".
This statement is false.
4. "Angle 4 is the angle of elevation from the radar tower to the person".
This statement is false.

Step-by-step explanation:
Answer:

Step-by-step explanation:
Given
i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)


If the three are to be next to each other,
First, we arrange the three

Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:

So, the total arrangement, when they have to be next to one another is:


The probability is:


Expand




Express as percentage


The correct answer is the correct answer... there is no question to be answered so there is no answer
Answer:
1/13
Step-by-step explanation:
In a deck of 52 cards, there are 4 kings
P(king) = number of kings / total cards
P (king) = 4/52
= 1/13
