The first thing we must do for this case is to find the relationship between the variables.

We have then:

AB = DC\\4y - 2 = 2y + 6

From here, we clear the value of "Y":

4y - 2y = 6 + 2\\2y = 8

y = \frac{8}{2}\\y = 4

On the other hand we have:

AD = BC\\3x - 1 = 2x + 2

From here, we clear the value of "x":

3x - 2x = 2 + 1\\x = 3

Then, replacing values we have:

AB = DC = 4y - 2 = 4 (4) - 2 = 16 - 2 = 14\\AB = DC = 14

On the other hand:

AD = BC = 2x + 2 = 2 (3) + 2 = 6 + 2 = 8\\AD = BC = 8

Finally, the perimeter is given by:

P = AB + DC + AD + BC

Substituting values we have:

P = 14 + 14 + 8 + 8\\P = 44

Answer:

the perimeter of ABCD is:

44 units

A hot air balloon is flying at an altitude of 800 feet. A passenger takes a picture of the top of a tree and estimates that the
nalin [4]

The height of the tree given the depression angle to the top and the base

is given by the tangent relationship of the two given angles.

Correct response:

  • The height of the tree is approximately <u>79.58 feet</u>
<h3 /><h3>Methods used for the calculation of the height of the tree</h3>

Given:

Altitude of the hot air balloon = 800 feet

Angle of depression to top of tree = 43°

Angle of depression to base of tree = 46°

Required:

Height of tree

Solution:

The horizontal distance of the balloon from the tree is given as follows;

  • \displaystyle tan(46^{\circ}) = \frac{Altitude \ of \ balloon}{Horizontal \ distance \ from \ tree} = \mathbf{\frac{800 \, feet}{Horizontal \ distance \ from \ tree}}

Therefore;

\displaystyle Horizontal \ distance \ of \ balloon \  from \ tree = \frac{800 \ feet}{tan(46^{\circ})}

  • \displaystyle tan(43^{\circ})  = \mathbf{\frac{Height \ of \ balloon \ above \ tree}{\dfrac{800 \, feet}{tan(46^{\circ})} }}

Therefore;

\displaystyle Height \ of \ balloon \ above \ tree = tan(43^{\circ}) \times \frac{800 \, feet}{tan(46^{\circ})}

  • Height of tree = Altitude of balloon - Height of balloon above tree

Therefore;

  • \displaystyle Height \ of \ tree = 800 \, feet - tan(43^{\circ}) \times \frac{800 \, feet}{tan(46^{\circ})} \approx \underline{  79.58 \, feet}

M&lt;1 = 95 and m&lt;2 =36: What is m&lt;7?<br><br> Answers and figure attached!
iren [92.7K]

∠7 = 59°

∠6 = ∠2 = 36° ( vertical angles )

∠4 = 180° - ∠1 ( straight angle )

∠4 = 180° - 95° = 85°

∠7 = 180° - (85 + 36 )° ( sum of angles in a triangle )

∠7 = 180° - 121° = 59°

Your sister says the horizontal measure from her to the rock wall is 5.5 feet, while the horizontal distance is 13.42 feet. What
denis-greek [22]

Answer:

12 feet

Step-by-step explanation:

Given in the question,

horizontal distance from sister to rock wall = 5.5 feet

diagonal distance from sister to rock wall's peak = 13.42 feet

<h3>To find the height </h3>

As we know this figure make a right angle triangle, so we will apply pythagorus theorem

hypotenuse² = height² + base²

13.42² = height² + 5.5²

13.42² - 5.5² = height²

149.85 = height²

height  = √149.85

height  = 12.24 feet

Approximate height of her rock wall to the nearest tenth =  12 feet

My name is Ann [436]

Answer:

\frac{3}{8} or 0.375

Step-by-step explanation:

The absolute value of a number is how far that number is away of zero.

|\frac{3}{8}|=\frac{3}{8}=0.375
