Answer:
the altitude of the helicopter is 3925ft
Step-by-step explanation:
we know the angle that is formed between the floor and the distance from the platform to the helicopter (73°)
and we know the distance of the platform (1200 feet)
at the angle we will call it α
and at the distance of 1200 feet we will call it adjacent
we want to know the height that in this case would be the opposite leg to the angle we have
we see that it has (angle, adjacent, opposite)
well to start we have to know the relationship between angles, legas and the hypotenuse
a: adjacent
o: opposite
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
it's the tangent
tan α = o/a
we replace the values and solve
tan α = o/a
tan 73 = o/1200
3.2708 * 1200 = o
o = 3925
This means that the altitude of the helicopter is 3925ft
The am not sure but i belive the answer is 74.60
Let Y be amount of times beat
let X be amount of time in seconds
the slope intercept form is y=mx+b
fill in the variables: y=30x
The correct answer is y=30x
Answer:
75% (Letter grade = C)
Step-by-step explanation:
- 15 ÷ 20 = 0.75
- Multiply by 100: 0.75 × 100 = 75
- So, your grade was a 75% (letter grade = C)
Answer:
- $14 discount
- $56 discounted price
Step-by-step explanation:
The amount of the discount is ...
20% of $70 = 0.20·$70 = $14 . . . discount
The discounted amount is ...
$70 -14 = $56 . . . discounted price
