Answer:

   = 11.4%

Step-by-step explanation:

Percent error = (target - actual)/target * 100

target = 2500

actual = 2215

Lets substitute in

Percent error = (2500-2215)/2500 * 100

                        = 285/2500*100

                       =.114 * 100

                      = 11.4%

What is the value of X?
sleet_krkn [62]

Answer:

  11/3 = 3 2/3 ≈ 3.66667

Step-by-step explanation:

The external angle is half the difference of the intercepted arcs:

  3x = (1/2)((9x +25) -36)

  6x = 9x -11

  11 = 3x . . . . . . . add 11-6x

  11/3 = x

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}
