Answer 3

oh 5/12

Answer 4

yup

Answer 5

can I ask more?

Answer 6

:)

Answer 7

sure why not?

Answer 8

btw you have my second favorite name on OS

Answer 9

The diagonals of kite KITE intersect at point P. Which statement is true?

Answer 10

to find m wouldnt you need to take tan-1(5/12)

Answer 11

tan^-1(5/12) sorry typo

Answer 12

Thank you @satellite73 what's your first favorite :)

Answer 13

@sweetburger no

Answer 14

i just said second because i didn't want to totally commit

Answer 15

alright

Answer 16

btw i am going to take a stab at this geometry, but no guarantees
what are the options for this "which of the following"

Answer 17

A) <KIE=<TPE
B) <TIP=<TPE
C) <KIT=<KET
D) <KPE=TPE

Answer 18

going to take a minute to go through all of these

Answer 19

the last one is true for sure

Answer 20

i think that is the only one

Answer 21

i was hoping for more trig

Answer 22

If TUVW is an isosceles trapezoid with TU/ parallel to WV/, name a pair of similar triangles. Explain.

Answer 23

WTV and WUV are similar
the diagonals have the same length, TW equals UV and angle W equals angle V

Answer 24

A.
triangle UXV= triangle WXT by the SAS similarity theorem.
B.
triangle TXU= triangle WXV by the SAS similarity theorem.
C.
triangle WUV= triangle TVW by the AA similarity postulate.
D.
triangle TXU= triangle VXW by the AA similarity postulate.

Answer 25

ughh... that took a long time.

Answer 26

yeah now let me check

Answer 27

ok first one looks good, but let me keep checking

Answer 28

not B

Answer 29

Ok :)

Answer 30

Verify the identity.

cos 4x + cos 2x = 2 - 2 sin2 2x - 2 sin2 x

Answer 31

hold the phone, not done with the previous one (i hate geometry)

Answer 32

same... I hate it too.

Answer 33

cause C looks good too
damn
lets move on

Answer 34

\[\cos (4x )+ \cos (2x) = 2 - 2 \sin^2( 2x) - 2 \sin^2(x)\] i am a bit confused with the 2's can you post a screen shot or is that it?

Answer 35

hey could we hold off on this problem for a sec, we'll come back to it. Is that fine?

Answer 36

sure

Answer 37

let me guess, more shape...

Answer 38

In the figure,line AB is parallel to line CD. If the area of triangle CED/ is 425, the area of BEA / is 68, and BE = 10, find CE.

Answer 39

yup lol.

Answer 40

A.
25
B.
36
C.
48
D.
62.5

Answer 41

the big triangle has area 425 and the small one area 68 is that right?

Answer 42

yes

Answer 43

ok we can do this

Answer 44

the ratio of the big area to the small area is \(425:68\) which reduces to \(25:4\)
or \(\frac{25}{4}\)
the ratio of the sides is therefore the square root of that, namely \(
\frac{5}{2}\)

Answer 45

since \(BE=10\) multply it by \(\frac{5}{2}\) and get \(25\)

Answer 46

Yea I did that.

Answer 47

ok good

Answer 48

what do I do next?

Answer 49

have a beer?

Answer 50

pick A we are done, the answer is 25

Answer 51

Find the equation of the circle that has a diameter with endpoints located at (-5,-3) and (-11,-3)

Answer 52

this is much easier

Answer 53

first find the midpoint
you got that?

Answer 54

do I have to type in the answer choices...

Answer 55

no we can knock this out in a heartbeat

Answer 56

what is the average of \(-5\) and \(-11\)?

Answer 57

you know what i mean? add them up, divide by 2

Answer 58

lol no

Answer 59

\[-5-11=-16\]
\[-16\div 2=-8\]

Answer 60

ok in any case that makes the midpoint \((-8,-3)\) so the equation is
\[(x+8)^2+(y+3)^2=r^2\]now we need \(r\)

Answer 61

the distance between \((-8,-3)\) and \((-5,-3)\) is evidently 3 (from -8 to -5 is 3 units) so \(r=3\)

Answer 62

final answer \[(x+8)^2+(y+3)^2=9\]

Answer 63

i hate to break it to you but i have no $%#@ing idea

Answer 64

Lol that alright, hold on.

Answer 65

repost i am sure someone knows this
and i am sure it is not me

Answer 66

Triangle GHI is similar to triangle JKL. If IH=36 and KP=18, LK=24 then MH=_____.

A.
12
B.
20
C.
27
D.
48

Answer 67

it take goddamn forever just to read it
hold on

Answer 68

@satellite73 That's fine for now we'll move on from that problem :) ^

Answer 69

no it is doable give me a sec

Answer 70

Lol alrighty.

Answer 71

\[\frac{18}{24}=\frac{3}{4}\] and so \[\frac{MH}{36}=\frac{3}{4}\] making \[MH=\frac{3\times 36}{4}\]

Answer 72

i hope 27 is a choice

Answer 73

it is ty!

Answer 74

whew
did i mention that i hate geometry?

Answer 75

Lol yes you did.

Answer 76

The diagonals of rectangle NOPQ intersect at point R. If OR=3x-4 / and NP=5x+20/, solve for x.

A.
2
B.
3
C.
12
D.
28

Answer 77

\[2\times OR=NP\] pr
\[2(3x-4)=5x+20\] solve for \(x\)

Answer 78

*or

Answer 79

6x-8=5x+20
-5x -5x

x-8=20
+8 +8
x=28 yay!

Answer 80

yay indeed
