The crane is 139.8cm tall.

<h3>what is angle of elevation?</h3>

The angle formed by the line of sight and the horizontal plane for an object above the horizontal.

Using Trigonometry

tan 30 = h/y

1/√3 = h/y

y= h√3

and, tan 25= h/y+62

         0.96= h/(h√3 +62)

             h= 0..96 (h√3 +62)

             h= 0.96*h*1.732+0.96*62

             h=0.796h +28.52

             0.2404h= 28.52

                  h= 139.8 cm

Hence, whooping crane is 139.8 cm.

<h3>The variable</h3>

This is the item that is being surveyed.

The surveyed item is birth weights

Hence, the variable is birth weights

<h3>The units of the variable</h3>

From the question, we have:

Average birth weight is 6 pounds 8 ounces.

Hence, the units of the variable are pounds and ounces

<h3>The population</h3>

This is the total number of babies in Southeast Asia

Hence, the population of interest is the babies in Southeast Asia

<h3>The individual</h3>

This is the people in the survey

Hence, the individual in the study is the 100 babies that were randomly surveyed

<h3>The parameter of interest</h3>

This is the value that gives the required information.

Hence, the parameter of interest is the average birth weight

<h3>What is the statistic involved</h3>

The statistic is the average

Answer:

V = 108,000,000pi or V = 339292007mm

Step-by-step explanation:

V = pi × r^2 × h

To find radius with circumference:

Radius = Circumference / 2pi

So, 1884/2pi = 299.847913 = 300

V = pi × 300^2 × 1200

V = pi × 90000 × 1200

V = pi × 108000000

V = 108,000,000pi or V = 339292007

(6x – 30° and m
k0ka [10]

9514 1404 393

Answer:

  48°

Step-by-step explanation:

Supplementary angles total 180°.

  m∠A +m∠B = 180°

  (6x -30)° +(8x +28)° = 180°

  14x = 182 . . . . . . . . . . . . . . . . divide by ° and add 2

  x = 13 . . . . . . . . . . . . . . . . . . . .divide by 14

Then the measure of angle A is ...

  m∠A = (6·13 -30)° = 6(13 -5)° = 6·8°

  m∠A = 48°
