Which angle is A? assuming the capital means angle and not side.

been a long time since i've done any maths, 49.4?

What angle is A?

11.66

area?

A is the universal symbol for area, so A=30

We're finished here.

i think 10 is only the length of the smaller triangle's edge not the whole length

Oh, well usually the triangle is labelled ABC for angles and abc for sides and i assumed finding the area is too easy, i was expecting to do some Pythagoras or Trigonometry.

The two triangles are going to be congruent, with the smaller triangle being a sixth the size of the larger one.

We have a hypotenuse length of (6^2+10^2)^(1/2) for the larger triangle, which is 2*sqrt(34). So the hypotenuse length of the smaller triangle is sqrt(34)/3.

The area of the full figure is bh/2=34/3.

you're right
because there is no indication what A is related to in the diagram presented

I assumed this for ().

>The two triangles are going to be congruent
Are they?

The diagram is mislabeled. The left edge of that drawing is 6 and bottom edge is 8. Thus the length shown as 6 cant actually be 6.

it's 30 you fucking retards

Yes.

I meant similar, not congruent. Bad English.

Why is that?

See ().

kek

what is a? make that clear before you have Sup Forums do your 5th grade maths for you

Trick question. The max height of a right triangle is half the hypotenuse.

Area

Ah, okay.

This is moot then.

It's not with the assumptions made.

That's easy... Sweden.

It's 50.8 retards. Total area of the entire shape

yeah, which fucking area? the one of the smaller upper/lower triangle or the one of the whole one? precision is the key to maths

It means area faggot

No it's not sorry. Trying to do this off iPhone calculator gimme a sec

Top: the smaller triangle has the same angles as the large one.

Apparently, see but i thought:

A=40.8
Small triangle has same angles of large one

Long side of triangle: 6
Short side of triangle: 6*.6
6*.6/2=10.8

Large triangle: 6*10/2=30
30+10.8=40.8

Is the 10 the total length of the two right angle triangles or the first I'm a little confused

34.98571137

I'ts 30 you cunts! area formula is (b*h)/2. Base given is 10 and height is 6

10 is portion of hypotenuse dumbass
I'm right

a lot of assumptions necessary

>assuming "A" stands for area

if 10 is the length of that entire side the answer is simply 30

how did you get that?
11.66 is the length of the hypotenuse for the larger of the 2 triangles. the full hypotenuse = 16.5 which give the area as 49.5

How did you get the full hypothenuse?

6^2+10^2 = 11.6
(11.6^2)x2 = 269 = 16.5

Oh bait, how I've missed thee!

I think it's wrong assumption that it's twice bigger. Can you explain?

if 10 is only the portion up to the intercept then the medium sized triangles hypotenuse is 11.66 or sqrt(136) and the opposite angle from the 6 (of the medium sized triangle is 30.96 degrees, which puts the hypotenuse of the entire triangle as 13.6 which makes the entire area as 40.8

yep i'm wrong, recalculating...

Total area = 40.8

Ok guys so
6^2+10^2=A^2
36+100=A^2
136=A^2
A=sqrt(136)=11.6

You are really bad at this

you assume that A refers to the length of that side and not the total area

I haven't had any paper.
It's midnight here and you faggots made me do maths. Fuck you.

now i get 43
11.6^2 + 8.7^2 = 212.5
= 14.6
14.6*6/2=43.7

well tell me what u need to have and i will do it for you

The height of the triangle is not 6, it can only be 5.
Short explaination, it's a right-angled triangle, the height can't be 6 if it's going to be a summary of 180 degree. Try putting the triangle in a circle, with the hypotenuse as diameter.

Conclusion, the height can only be 5, therefore, the area 25

see
you have really shitty spatial reasoning

height is 6

Mine is right, I did tons of similar tasks this year. Basically all you need is Pythagora's theorem and sine-cosine-tangens, as you see bihgest triangle and medium triangle share the same angle.

If 10 is the length of the full line then A = 30, if 10 is the length of the longer section of the line then A = 40.8, this is maths a 10 year old could do...

yup, but you were slow to it, other people already solved it in thread

total AREA = 42,7

most people dont know sin-tan-cos until they take geometry which is either in middle school or high school depending on state

either way not 10, but close to it

Yeah, I was trying to visualise it to people who do not understand.
And I was looking for piece of paper and pencil and calculator, without much success.

40.81

I got 44.8 when I assumed that 10 was the length of the entire side, and I got what you got when I assumed it was a section.

Not sin tan or cos. Simple half base times height.

this

41.0Cm^2

I concur gentlemen.

40.8, right?

The lowest side has lenth √(10**2+6**2) = 2√34
All triangles are proportional.
The side to the left = x => 2√34/x = 10/6 => x = 6√34/5
A = 1/2 * 6√34/5 * 2√34 = 40.8

Got the same answer. The 2 triangles making up the complete triangle are similar. Since the ratio between the height and length is 1:0.6 we get that the height of the small triangle is [6*0.6=3.6]. Hence the base of the complete triangle is 10+3.6=13.6 and from here it's the standard triangle area equation b*l/2=A => 13.6*6/2=40.8 => A=40.8

seriously... are you really this retarded or is this just more bad b8

hell yeah!

I'm sure it's already been said but didn't read. This triangle cannot exist since the hypotenuse is 10 and the opposite angle is 90, the maximum height is 5.

The hypotenuse isn't 10, user.
I know, the instructions could've been clearer.

correct. i was taught that the hypotenuse was opposite the 90 degree angle.

law of cosine you fucking idiots

Hmm, I've got this.

(pi * r + 6/ square root) + 10 cubed - (12 dildo)

the answer is nigger

This question was used on a microsoft job interview, it was to test the ability to analyze and keep a cool mind. The point was to realize that the height can't be 6. Not going to explain more, try search this on google

thanks OP

you're a fucking retard

you're a retard. 40.8

10 to 6 ratio..works here so really simple.

6 x 0,6 = 3,6
3,6 x 6 = 21,6 / 2 = 10,8

6x10= 60 /2 = 30

30+10,8 = 40,8

Nice

well, look at OPs picture. the position of the 10 does not at all suggest it is meant as the whole hypothenuse.
it the article it's not as extreme, but still pretty bad.
whoever thought that up needs to get slapped.
