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 = \frac{\text{\text{Opposite side}}}{\text{Hypotenuse}}

sinθ = \frac{AB}{AC}

AC = \frac{AB}{sin\theta }

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.

Answer:

( 11   -6)

( -5   6 )


Step-by-step explanation:

Multiply the first row of N by first column of M. This will give the first  element in top row of the answer :-

-3*-2 + 1*5 =  11

Then multiply the first row in N by the second column of M to give the second element of the top row.

-3*0 + 1*-6 =   -6

Then do a similar process with the second row in N.

Y - x = 6
y + 2x = 57 

2y - 2x =12
y + 2x = 57 

∴3y = 69
   y = 23
 

23 - x = 6 
-x = -17 
x =17

large van = 23
small van = 17
