The sum of the interior angels is 180(n-2). In this case 180(5-2)= 540. So the equation is 540=100+103+4x+(3x+3)+(5x-2). Then solve for x. X=28

Answer:

Equation: 540=(4x)+(3x+3)+100+103+(5x-2)

x=28

Step-by-step explanation:

540° in a 5 sided polygon

so knowing that

540=(4x)+(3x+3)+100+103+(5x-2)

Combine Like Terms

540=(4x+3x+5x)+(3+100+103+−2)

540=12x+204

flip equation

12x+204=540

subtract 204 from both sides

12x=336

divide both sides by 12

x=28

To measure the height of the cloud cover at an airport, a worker shines a spotlight upward at an angle 75° from the horizontal.

DaniilM [7]

The geometry of the problem does not seem well-described here. Assuming the spotlight beam and the observation are in the same vertical plane, there are two possibilities for the height:
.. 446 m . . . . . spotlight is aimed toward observer
.. 772 m . . . . . spotlight is aimed away from observer

See the attachment for the geometry. Choose the answer corresponding to the geometry of the problem.

Use the PEMDAS rule you learned in elementary. First do the exponent that is -9 with 10 then multiply the denominator ( the bottom of fraction) and lastly divide 0.09 divided by what the denominator is.

By how many days should each activity be crashed to reduce the project completion time by 4 days? fill in the table below. (en

butalik [34]

A project with a completion time of more than 4 days with several identified activities can be reduced to a completion time of 4 days. This can be done by adjusting the activity timeline of the project and eliminating some of the slack time to meet the earlier completion date. Also, some of the activities can be done in parallel to maximize the time given for the project to be completed. For example, activity A can be done simultaneously with activity B before it proceeds to activity C. You can also use PERT-CPM tool to identify the shortest possible time for project completion.
