Answer 41

This is about grade 9 or 10 stuff; mostly similar triangles - which means is can mostly be done with algebra.

Answer 43

Eh...

Answer 44

Too many questions, a different language in this post. Super confused what has to be done and what haasn't...

Answer 45

hasn't*

Answer 46

This should help you... http://www.mathsisfun.com/geometry/triangles-similar.html

Answer 47

all the questions on what I posted before any one got on ay itnd okay ill try

Answer 48

okay no not going to help me idk what im doing what so ever

Answer 49

I believe I got the first one. I show you how I did it:

Answer 50

awesome ty

Answer 51

Similar triangles by side-angle-side relationship... so the small triangle at the top is equal to the big triangle around the whole outside.

therefore, the ratio of the small triangle (LENGTH of right side divided by LENGTH left side) is EQUAL to the ratio of the big triangle (LENGTH of right side divided by LENGTH of left side). That gives you the following:

\[\frac{ 12 }{ 9} = \frac{ 3x + 2 + 12 }{ 4x - 2 + 9 }\]

See how the big triangle includes the lengths of the sides of the smaller triangle? That's because the whole large triange is similar to the whole small triangle.

Answer 52

Solve for x, and you'll get your answer.

Answer 53

can u help me with the other ones.. ik thats alot to ask but im a blonde and my hair seriously gets to me

Answer 54

I could definitely help with a few. Just give a me couple of seconds, as I got a couple people asking for my attention, lol. How about the second one? You have that one yet?

Answer 55

no i have the one u helped with and what is the geometric mean between 5 and 12? how?

multiply 5 and 12 = 60 and take the square root.

2 square root 15

Answer 56

that looks right to me. you multiply the two numbers, then take their root, which is sqrt(60).
or 2*sqrt(15).

Answer 57

yes

Answer 58

??

Answer 59

I'm looking at the second problem, but it doesn't appear to be 2 similar triangles... it seems a bit trickier; looking for a solution though.

Answer 60

KK

Answer 61

@whydoihavetosignup1

Answer 62

HELLOO:)

Answer 63

Hey. :D
I got an answer for number 2 the ...complicated way using geometry. However, if this problem is supposed to be simpler, then I'm certain the ratios are supposed to be:

\[\frac{ 9 }{ x } = \frac{ 15 }{ 25 }\]

But there's a reason I doubt myself... but it's the best I can come up with at the moment given my divided attention, lol

Answer 64

3rd question is about congruency of the two triangles (Hint. Angle-side-angle)

Answer 65

look at multiple choices im confused on the .................. dude..... idk i think ima just fail

Answer 66

the next one:
\[12^{2} + h^{2} = y^{2}\]
\[16^{2} + h^{2} = x^{2}\]
\[x^{2}+y^{2} = (12+16)^{2}\]

these 3 equations manipulated should help you find the answer.

Answer 67

to all three?

Answer 68

I wouldn't be so quick to say you'll fail. I barely passed highschool math, now I'm in school for engineering, lol.
Yeah, it's not easy to get know... but later you'll look back, and wonder why it was so tough...
Just don't talk yourself out of it. XD

Answer 69

what about 4 5 6

Answer 70

no, the last one were all equations to solving 5.diagram.png.

Answer 71

those three equations are needed to solve it. If you look in the diagram, there are 3 right triangles.

Answer 72

i want to be a doctor.. so im trying but cant get the hang of it

Answer 73

and ok

Answer 74

cool. when I'm done engineering, I'm going to apply to med school; so I think we're kinda in the same boat. XD

Answer 75

lol cool:)

Answer 76

did you get an answer for diagram 5?

Answer 77

im confused?
