Question

It's a picture, but I will try to describe it the best I can. It's a right triangle, the base is unknown, the side is 8, and the hypotenuse is 17. I know you have to do pythagorean thereom, i did it and you get 15, it was simple. then I added 15 to 8 and 17, and I got 40, but that's not one of the answer choices on the review.. the closest is 46..

Answer 1

So, your triangle would like... something like this.

Answer 2

yesss

Answer 3

omg, i had no idea you could add drawings on here

Answer 4

And you want to find the
unknown side-- which is the Pythagorean Theorem:\[a^2 + b^2 = c^2\]

c = hypotenuse ; a & b are the sides.

Answer 5

Haha, yes! You can! he draw button. :)

Answer 6

yes, i found x, it is 15, but idk what to do next i added all the sides.. but i got 40 which isn't the right answer

Answer 7

Is it more than just finding the length of the unknown side?

Answer 8

you have to find the perimeter, oops i think i forgot to mention that

Answer 9

Well, does the question ask for more than that?

Answer 10

so like when you find the unknown side you have to add everything together.... here are the answer choices: 15, 33, 46, 50

Answer 11

omg, wait i think i know, ima upload the pic

Answer 12

You're positive it's perimeter and not area? Just making sure. :)

Answer 13

its actually a rectangle, so like half of it is a triangle, so i just saw the triangle and thought you have to do the pythagorean thereom, but maybe you have to do something else..

Answer 14

yes, im positive its not area

Answer 15

Ah, okay. I was a bit confused there.

Answer 16

i found this formula on google for perimeter for this type of problem: Perimeter = 2L + 2 ( \/ (D^2 - L^2) do u think its right? maybe i should try it and see if i get one of the answers

Answer 17

i dont get what that V stands for or whatever it is..?

Answer 18

i have 45 mins left for 13 problems :/

Answer 19

I don't get that, either. Geometry isn't really my strong suit, but I'll show you what I did.

Answer 20

ok

Answer 21

OMG i got it!!!!

Answer 22

its 46

Answer 23

Since it's a rectangle, and it's being cut by a diagonal, I assumed that the two triangles would have an equal area.

Answer 24

its not with that long formula btw

Answer 25

That was the same answer I got as well. I'll upload the picture that I worked out on my tablet.

Answer 26

i did P= 2(8+15) = 46

Answer 27

ok :)

Answer 28

Sorry that it took a bit; but, her eyou go. :)

Answer 29

its ok.. thanks :)

Answer 30

I hope it kind of helps; was kinda in a rush to see if I could help you. So, it's kinda messy. xD

Answer 31

Answer 32

All right, good! Do you need help with anything else? :3
