Answer:
Distance between the person and the plane is 12 miles
Step-by-step explanation:
From the figure attached,
An airplane is flying at an altitude AB = 6 miles.
An observer is standing at point C from where he observes the plane at an angle of elevation θ
Therefore, sinθ = 
sinθ = 
AC = 
AC = 6cosecθ
If angle θ = 30°
Then AC = 6cosec30
AC = 6×2
AC = 12 miles
Therefore, distance between the person and the plane is 12 miles.
if interior angle is 170, subtract 170 from 180 to find exterior angle:
180-170 = 10 = exterior angle
the sum of exterior angles is 360 so divide by exterior angle to find sides:
360 /10 = 36 sides
9514 1404 393
Answer:
160 cm³
Step-by-step explanation:
The ratio of the linear dimensions is the square root of the ratio of areas:
scale factor B/A= √(64/144) = 8/12 = 2/3
The ratio of volumes is the cube of the scale factor:
(volume B)/(volume A) = (2/3)³ = 8/27
Then the volume of pyramid B is ...
volume B = (volume A) × (volume B)/(volume A)
= (540 cm³) × (8/27) = 160 cm³ . . . . volume of pyramid B
_____
Equivalently, the ratio of volumes is the 3/2 power of the ratio of areas.
Vb = Va(64/144)^(3/2) = (540 cm³)(4/9)^(3/2) = (540)(8/27) cm³ = 160 cm³
Answer: what I understood from the question that you want this side and the other side so the fust side equals 33 and the second side after the equal side equals -20 so 33 = -20
Step-by-step explanation: I hope it is correct .
