What is the measure for the following ∠?<br> m∠BOA<br><br> 20<br> 40<br> 60
kaheart [24]

Hello!

First, find angle BOA on the protractor. To do this, look for point B, point O, and point A.

Now, we see some markings that mark what degree point B and point A are at. Point B is marked at 60 degrees, and Point A 40 degrees.

Now, all that's left to do, is subtract the two measurements.

60 degrees - 40 degrees = 20 degrees

Therefore, your answer is 20.

Hope this helps!

Solve similar triangles (basic)
fiasKO [112]

Answer:

<em>T </em><em>=</em><em> </em><em>1</em><em>6</em>

Step-by-step explanation:

As triangles are similar

AB/DE = BC/EF = AC/DF

13.5/18 = 6/4 = 12/T

3/4 = 3/4 = 12/T

3/4 = 12/T

T = 12×4/3

T = 16

A) given that in 2019 you were among the 21.11% of the best students in the class, in that year you had the higher percentile ranking, and B) the measure of average that would be the most meaningful is the median.

Given that your class rank in 2018 was 89 out of 360 students, while in 2019 your class rank was 95 out of 450 students, to determine A) in which year did you have the higher percentile ranking, and B) if you had the data on the cumulative GPA of each student at the end of the spring semester in 2018, which measure of average would be the most meaningful - mean, median or mode -, the following calculation should be performed:

  • 360 = 100
  • 89 = X
  • 89 x 100/360 = X
  • 24.72 = X
  • 450 = 100
  • 95 = X
  • 95 x 100/450 = X
  • 21.11 = X

Therefore, A) given that in 2019 you were among the 21.11% of the best students in the class, in that year you had the higher percentile ranking, and B) the measure of average that would be the most meaningful is the median.
