Answer:
42 students
Step-by-step explanation:
We can find the height of the altitude by the ratio of sin. See my attachment.
sin of angle = side in front of the angle / hypotenuse
sin x = height/distance
If the two pilot is rising in an hour, then the first distance is 400 miles, the second distance is 300 miles.
Find the height of first pilotheight/distance = sin x
height/400 = sin 30°
height = sin 30° × 400
height = 1/2 × 400
height = 200
Find the height of second pilotheight/distance = sin x
height/300 = sin 40°
height = sin 40° × 300
height = 0.642 × 300
height = 192
So the first pilot traveling 400 mph with 30° is more quickly to reach high altitude than the second pilot traveling 300 mph with 40°
I beleive that it would be C=n25
Step-by-step explanation:
I'm not sure if this is not complex enough but I'm just going by what I think this is.
There are going to be two solutions because the "biggest" x is x^2 but you can factor to find what they actually are.
Answer:
A.
Step-by-step explanation:
EF^2=18^2-12^2
EF^2=324-144
EF^2=180
EF=root 180
