Question

In the figure, 12 years ago

Answer 1

theorem
not to scale

Answer 2

How? D:

Answer 3

do you know the pythagorean theorem?

Answer 4

Yep, but is there enough info?

Answer 5

Cause my teacher says this is solvable but I tried finding that length, but i dont think theres enough info

Answer 6

Or am i wrong

Answer 7

total length of
JL is?

Answer 8

20

Answer 9

length of
ML is?

Answer 10

I only found one side length of each triangle. :(

Answer 11

ML is 4

Answer 12

so if i have
JM =
ML = 4

Total JL = 20

Answer 13

JM = 16

Answer 14

so you got the length of the other side :)

Answer 15

What? Dx I'm confused

Answer 16

you do not understand how you got this?

Answer 17

I only found one side of each triangle. I don't get how this will help me. Sorry, very bad at math. ToT

Answer 18

the other side is given

Answer 19

the length of
KM is given

Answer 20

it is?

Answer 21

what, i thought we had to find it

Answer 22

yep
look at your problem again :)

Answer 23

In the figure, <JKL is a right angle and line KM is the altitude. Find the missing lengths.

Line JL = 20, Line ML = 4, Line KM = ?

Answer 24

KM isn't given D:

Answer 25

wait

Answer 26

i thought it was a 7

Answer 27

lol

Answer 28

oh xD That's okay. Reading things wrong happens to me to. :P

Answer 29

hmm
have you every heard of the
30 60 90 triagle

Answer 30

Yep, but my geometry sucks because of my horrible geometry teacher in 8th grade. ;_;

Answer 31

How can you be sure it's 30 60 and 90 triangle?

Answer 32

lol
right angle

Answer 33

you can easily tell

Answer 34

Are you sure that's enough DX

Answer 35

So, are you saying all three triangles are 30, 60, and 90 triangles?

Answer 36

yep you can tell

not to scale

something like this
is a 30 60 90 triangle

Answer 37

yeah

Answer 38

Yea, but my picture isn't drawn to scale to, since JM is like way bigger than ML

Answer 39

but i assure you that's the exact drawing my teacher provided ToT

Answer 40

but it is
a given

Answer 41

So we're just suppose to assume?

Answer 42

Should I just rely on the 30, 60, and 90 triangle since I can't find any other information?

Answer 43

This problem actually had additional parts to it. Like, he also gave us JL = 18, KL = 112, ML =? This problem was easy for me since all I had to do was trigonometry but the angles I found weren't 30, 60, and 90 like it appears. So you can see why I'm really tentative about it. T_T

Answer 44

Sorry, can you specify which triangle you are altering since there are three? Is this triangle JMK?

Answer 45

hmm
am not altering
this is a special relationship

Answer 46

let me take this piece by piece
what is the total angle measurements inside a triangle

Answer 47

I know, but like altering into a more accurate form from given triangle xD

Answer 48

That is not given
Only the drawing and lengths were

Answer 49

total measurements of a triangle contain
180 degrees

JKL (given right angle) = 90
KJL =
KLJ =
180

Answer 50

My teacher is somewhat a sadist. He enjoys it when he gives students difficult problems such as this but he is smart and knows there is a way to solve this. T_T

Answer 51

then you be smart also
say its a 30 60 90 triangle and laugh at his face

Answer 52

i feel like your going to curse at me for not helping you :(

Answer 53

is it really? T_T i really want to make sure. he always makes his test so hard :\ and i just want to find out to ace his class next year. so much ppl get there gpa destroyed because of him

Answer 54

No, what D: im not that type

Answer 55

im just hoping for a genius to come by and know a solution xD

Answer 56

30
60
90
---
180 inner angle measurement of triangle

Answer 57

Wait so we're just going with the fact that all three triangles are 30, 60, and 90 ones right?

i dont know if these can help

Answer 59

umm yes these are 30 60 90
triangles

Answer 60

there are a bunch more on google :P

Answer 61

Okay, I guess that's the only way to solve this problem, can't think of another way to find the angles.

And I know why you think it is. It's cause they appear like it, but what if there off by only a little and just give off a fake appearance of a 30, 60, and 90?

Answer 62

this is only if it is not a given
and only
if there is no angle with a

not to scale
on it

Answer 63

you would need more info

Answer 64

Okay, thanks. xD I thought there was a magical way to get an angle with the given info but now I'm more confident that it is a 30, 60, and 90. Thanks, I'll just base it off that assumption. xD And you're right, it wouldn't be solvable without extra info. :)
