Pls help:) (geometry)

Mathematics
1 answer:
dybincka [34]3 years ago
7 0

Answer:

see explanation

Step-by-step explanation:

(15)

Since BE bisects ∠ ABD then ∠ DBE = ∠ ABE, thus

8x - 14 = 6x + 2 ( subtract 6x from both sides )

2x - 14 = 2 ( add 14 to both sides )

2x = 16 ( divide both sides by 2 )

x = 8

Thus ∠ ABE = 6x + 2 = 6(8) + 2 = 48 + 2 = 50°

(16)

Since BE bisects ∠ ABD then ∠ ABE = ∠ DBE = 12n - 8 and

∠ ABD = ∠ ABE + ∠ DBE, that is

22n - 11 = 12n - 8 + 12n - 8 = 24n - 16 ( subtract 24n from  both sides )

- 2n - 11 = - 16 ( add 11 to both sides )

- 2n = - 5 ( divide both sides by - 2 )

n = 2.5

Thus

∠ EBD = 12n - 8 = 12(2.5) - 8 = 30 - 8 = 22°

Studentka2010 [4]

The median, upper and lower quartiles of the data set are:

Lower Quartile = 46

Median = 49

Upper Quartile = 90

<h3>What is the Median?</h3>

The center value or middle value of a data set is the median.

<h3>What are the Upper and Lower Quartiles?</h3>

Upper quartile (Q3) is the center or middle data point of the second half of a data set.

Upper quartile (Q3) is the center or middle data point of the second half of a data set.

Order the data set given as:

32, 46, 49, 49, 77, 90, 96

Lower Quartile = 32, (46), 49, 49, 77, 90, 96 = 46

Median = 32, 46, 49, (49,) 77, 90, 96 = 49

Upper Quartile = 32, 46, 49, 49, 77, (90,) 96 = 90

Erin has scanned a 4 × 5-inch postcard, and she wants to reduce it to make a graphic for her Web site. She will use a scale fact
Rasek [7]
Just multiply both dimensions by 2 to make it into centimeters.

Therefore,

4*2 x 5*2 (in inches) will be:

8cm x 10cm (in centimeters)

We conclude that the dimensions of her postcard into a graphic on her web page will be 8x10 in centimeter units. 

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
