Answer:

$arc\ DBE=206^o$

Step-by-step explanation:

The picture of the question in the attached figure

The question is

Find the measure of arc DBE

step 1

Find the value of k

we know that

$m\angle EPC=90^o$ ----> by quarter of circle

$m\angle EPC=(33k-9)^o$

$(33k-9)^o=90^o$

solve for k

$33k=90+9\\33k=99\\k=3$

step 2

Find the measure of angle DPC

we know that

$m\angle DPC=(20k+4)^o$

substitute the value of k

$m\angle DPC=(20(3)+4)=64^o$

step 3

Find the measure of angle BPD

we know that

$m\angle BPD+m\angle DPC=90^o$ ---> by complementary angles

substitute the given value

$m\angle BPD+64^o=90^o$

$m\angle BPD=90^o-64^o=26^o$

step 4

Find the measure of arc DBE

we know that

$arc\ DBE=arc\ DB+arc\ BAE$

$arc\ DB=m\angle BPD=26^o$ ----> by central angle

$arc\ BAE=180^o$ ---> because a diameter divide the circle into two equal parts (BE is a diameter)

substitute

$arc\ DBE=26^o+180^o=206^o$

Ax-b=c solve for b A- b= -ax-c B- b=ax+c C- b= -ax+c D- b=ax-c

Alex

Ax - b = c....subtract ax from both sides
-b = -ax + c <==
or it could also have been b = ax - c (but that ones not there)

How can the Angle-Angle Similarity Postulate be used to prove the two triangles below are similar? Explain your answer using com

zloy xaker [14]

To use the AA postulate directly, you need to show that two corresponding angles are congruent. In order to show that here, you must calculate the value of one of the missing angle measures. Either of the missing angles can be found by invoking the fact that the sum of angles in a triangle is 180°.

After finding either missing angle, you can show that the measures of two angles in one triangle are identical to the measures of two angles in the other triangle, hence the triangles are similar by the AA postulate.

Is it true that the order when dividing 3 real numbers does not affect the answer

Jobisdone [24]

No, it is not true

Lets do an example:

4 divided by 2 divided by 1 equals 2, while 2 divided by 1 divided by 4 equals 0.5
