Answer:
The angle of depression for the flight part is approximately 0.2604 degrees
Step-by-step explanation:
The given altitude at which the helicopter is flying = 50 meters
The horizontal distance of the helicopter from the helipad = 11 kilometers = 11,000 meters
The angle of depression = The angle of elevation = Arctan(Altitude/(Horizontal distance)
Therefore;
The angle of depression for the flight part = Arctan(50/(11,000)) ≈ 0.2604 degrees
Answer: 1/2, 1/2, 1/4
Step-by-step explanation:
To find the fraction that the hour hand turns of a clockwise revolution, we have to find how long it is going then divide by 12
Ex. a) 11 - 5 = 6, 6/12 = 1/2 so the hour hand turns by 1/2 of a clockwise revolution
b) 8 - 2 = 6, 6/12 = 1/2 so the hour hand turns by 1/2 of a clockwise revolution
c) For this, we have to convert 1 into 13 as 1 - 10 is a negative number
13 - 10 = 3, 3/12 = 1/4 so the hour hand turns by 1/4 of a clockwise revolution
Answer:
2
Step-by-step explanation:
Since if it's 5 or higher you go up but if it's 4 or lower you stay the same. And since 2.36 doesn't have the .5 it would round to 2
