Triss [41]

Answer:

the answer i got was 1159.1

Step-by-step explanation:

cos75 = 300/x

0.25881905 = 300/x

multiply everything by x

0.25881905x = 300

Divide everything by 0.25881905

x = 1159.1

is that close to any of your answers?

Answer:

$arc\ DBE=206^o$

Step-by-step explanation:

The picture of the question in the attached figure

<u><em>The question is</em></u>

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

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

Answer:

540°

Step-by-step explanation:

If a triangle (3 sides) has 180 degrees then we can figure out the degrees in a pentagon.

180° + 360° = 540°

How? The "top" part could be seen as a triangle (180 degrees), and we know that a quadrilateral's angles add up to 360 degrees, so when we add them together we get out answer!
