Answer:

x = 80

Step-by-step explanation:

We know AEC + CEB = 180 since it forms a line

AEC + 160 = 180

AEC = 20

We also know that

AEC + AEF + FED = 180 since it forms a line

20 + x+ 80 = 180

Combine like terms

100 +x = 180

Subtract 100 from each side

100+x-100= 180-100

x = 80

Suggest a fundamentally and conceptually different way that is always under the control of the researcher of making the margin o

SVEN [57.7K]

Step-by-step explanation:

First, we may wonder, what does the term margin of error mean? Put simply, the margin of error is a measure of the degree to which research results do not reflect the views of the total studied population. In other words, it tells readers how much confidence they should have in the results presented.

It has often been suggested that a fundamentally and conceptually effective way that is always under the control of the researcher of making the margin of error smaller is to increase the sample size of the research. This basically involves collecting more sample data which thus leads to a closer estimate of the view of the entire population.

Quadrilateral ABCD is inscribed in this circle.

Alecsey [184]

The sum of all interior angles in a polygon is

180(n-2), where n = sides, well, this is a QUADrilateral, so it has 4 sides, so the total is 360°.

now, let's find what angle C is first,

$\bf \stackrel{A}{(2x-40)}+\stackrel{B}{(116)}+C+\stackrel{D}{(x)}=360\implies C+3x+76=360
\\\\\\
C+3x=284\implies C=284-3x$

now, recall the "inscribed quadrilateral conjecture", where opposite angles are "supplementary angles", thus

$\bf \stackrel{\measuredangle A}{(2x-40)}+\stackrel{\measuredangle C}{(284-3x)}=180\implies -x+244=180
\\\\\\
64=x\\\\
-------------------------------\\\\
\measuredangle A=2(64)-40$
