Hellppp guys

OpenStudy (anonymous):

OpenStudy (anonymous):

Thats actually the wrong answer.

OpenStudy (anonymous):

That is why I posted it on here.

OpenStudy (anonymous):

I don't need to show you my work. wth?

OpenStudy (anonymous):

You show me how I did it wrong

OpenStudy (anonymous):

In similar triangles, corresponding sides are in equal ratio Here the hypotenuse of the big triangle vs hypotenuse of small triangle is 25/15

OpenStudy (anonymous):

So I simplify 25/15?

OpenStudy (anonymous):

No, now considering the perpendiculars, a and 9 should equal the same ratio 25/15 so we write them equal a 25 ----- = ------ 9 15 multiply both sides by 9 and simplify on right side a = 15

OpenStudy (anonymous):

And for b?

OpenStudy (anonymous):

similarly, b 25 ----- = ------ 12 15 multiply both sides by 12 b=20

OpenStudy (anonymous):

I have next one also buddy

OpenStudy (anonymous):

OpenStudy (anonymous):

should be 330 degree as they are congruent triangles and C <--> C'

OpenStudy (anonymous):

Thats the wrong answer buddy

OpenStudy (anonymous):

sorry i meant 33 degree

OpenStudy (anonymous):

OpenStudy (anonymous):

This one too paaji

OpenStudy (anonymous):

This one u shud b able to solve using Pythagoras theorem (Hypotenuse)^2 = sam of squares of other two sides

OpenStudy (anonymous):

So a2 plus b2= c2

OpenStudy (anonymous):

Yes, which translates to 17^2 = 8^2 + a^2 because the longest side is hypotenuse

OpenStudy (anonymous):

So what would be the accurate answer?

OpenStudy (anonymous):

17^2 - 8^2 = a^2 Calculate the left side first.....say u get X then a = squareroot of X

OpenStudy (anonymous):

left side 34

OpenStudy (anonymous):

17 x 2

OpenStudy (anonymous):

right side is 16

OpenStudy (anonymous):

no 17^2 means square of 17

OpenStudy (anonymous):

17^2 - 8^2 = a^2 289-64 = a^2 a= squareroot of 225

OpenStudy (anonymous):

a=15

OpenStudy (anonymous):

Te perimeter ki haga

OpenStudy (anonymous):

for perimeter add lengths of all three sides as perimeter is the total length of the boundary of a closed figure

OpenStudy (anonymous):

Phir area?

OpenStudy (anonymous):

1/2 * base (15) * height (8)

OpenStudy (anonymous):

1/2 ki hunda?

OpenStudy (anonymous):

Mainu na tussi final area da answer dedo

OpenStudy (anonymous):

half 1 -- 2

OpenStudy (anonymous):

60
