What is the description of angle 4 as it relates to the situation below?
2 answers:
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."

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.

Answer:
Step-by-step explanation:
Total number of cards in a standard deck = 52
Number of hearts in the deck = 13
Number of clubs in the deck = 13
Number of diamonds in the deck = 13
Number of spades in the deck = 13
Four cards are drawn at random by Timothy.
These four cards are drawn from each one of the suits.
And the cards are not replaced.
Therefore, now cards remaining in each suit:
Remaining number of hearts in the deck = 12
Remaining number of clubs in the deck = 12
Remaining number of diamonds in the deck = 12
Remaining number of spades in the deck = 12
Formula for probability of an event E can be observed as:
Here, number of favorable cases are 12 (i.e. number of hearts)
Total number of cases = 12 4 = 48
Therefore, the required probability is:
