Answer:

A and D are equal

Step-by-step explanation:

Given

$A=-2[-6, 4, 3 ,7, 12, 10]$

$B=3[-2, 2, 8, 8, 5, 6]$

$3C=3[-2, 8, 2, 5, 8, 6]$

$D=-1[-12, 8, 6, 14, 24, 20].$

Required

The equal matrices

First, we simplify the given expressions

$A=-2[-6, 4, 3 ,7, 12, 10]$

Open bracket

$A= [12, -8, -6 ,-14, -24, -20]$

Next:

$B=3[-2, 2, 8, 8, 5, 6]$

Open bracket

$B=[-6, 6, 24, 24, 15, 18]$

Next:

$3C=3[-2, 8, 2, 5, 8, 6]$

Divide by 3

$C=[-2, 8, 2, 5, 8, 6]$

Lastly:

$D=-1[-12, 8, 6, 14, 24, 20].$

Open bracket

$D=[12, -8, -6, -14, -24, -20].$

By comparison:

$A = D=[12, -8, -6, -14, -24, -20].$

From the top of a vertical tower, 331 feet above the surface of the earth, the angle of depression to a doghouse is 28 degrees 8

Elena L [17]

Answer:

619.13 feet

Step-by-step explanation:

Please find the attachment.

Let x represent the distance between doghouse to the foot of the tower.

We have been given that from the top of a vertical tower, 331 feet above the surface of the earth, the angle of depression to a doghouse is 28 degrees 8'. We are asked to find the distance between doghouse to the foot of the tower.

First of all, we will convert our given angle into degrees as it is given in degrees and minutes.

We will divide 8 by 60 to convert 8 minutes into degrees as:

$\frac{8}{60}=0.13333$

The doghouse, tower and angle of depression forms a right triangle with respect to ground, where, 331 feet is opposite side and x is adjacent side to angle 28.13 degrees.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$
