Question

how do i find the area of a scalene triangle

the bottom of the scalene triangle says 8.7km but doesn't say anything else

Answer 1

There is insufficient information.

Answer 2

ill show you a picture

Answer 3

With angle measurements you may be able to find the other sides.

Answer 4

its number 64

Answer 5

Nope. That's silly. There must be more information or it cannot be done.

Answer 6

how do i do angle measurements do find the other sides?

Answer 7

Agree^^ Even if we knew it was a right triangle, that would not be enough

Answer 8

how do i find the angle measurements for the other sides*

Answer 9

Well you could use a protractor. But that wouldn't be exact.

Answer 10

I noticed in the other drawings they did not label if right angles are formed which is a bad play on their part because this does not allow us to identify any information but considering it is a scalene triangle we know all sides and all angles are not the same. So without an angle measurement we wont be able to fine the area of the triangle.

Answer 11

Did they give any other information at all?

Answer 12

npe so do i just use a protractor

Answer 13

It would not be a bad move. Otherwise, leave it as the formula for a triangle with the base included and indicate the problem does not provide enough information to solve.

Answer 14

so i would do 8.7/2

Answer 15

1 more question, is it indicated that the triangle you're working with is scalene?

Answer 16

nope it doesnt

Answer 17

How do you know it is scalene?

Answer 18

it looks exactly like one....and theres even another triangle like a regular one that only shows 5km on the right side

Answer 19

There are other triangles that 'look' like they are scalene but may actually be an 90, 60 30 triangle.

Answer 20

If we assume that the triangle is 90, 60 30. We can solve it.

Answer 21

ok let me check

Answer 22

If we are not told any special info about the triangle, it is best to assume a scalene triangle.
