Question

Compute the area of a triangle with sides.

10 x 10 x 16

a = ___ square units

Answer 1

axbxc

Answer 2

1,600

Answer 3

nopes, use Heron's formula

Answer 4

10 10 8

Answer 5

I like to picture it then you can figure it out often without remembering a formula.

Answer 6

10^2x10^2x8^2

Answer 7

i have a doubt @just.chris how do u know that the perpendicular line drawn also bisects the side?? how do u get 8 ?
sorry if i am interrupting.....

Answer 8

\[\LARGE{\color{Red}{Heron's \space Formula:-}}\]\[\LARGE{\color{green}{\sqrt{s(s-a)(s-b)(s-c)}}}\]where,\(\Large{\color{blue}{s=\frac{1}{2}(a+b+c)}}\)

Answer 9

find s first of all :)

Answer 10

10x10x16

Answer 11

& then put the values in the formula to get ur answer :)

Answer 12

10 x 10 x 16 is an equilateral triangle.

Answer 13

@just.chris no, its not equilateral.......

Answer 14

isosceles triangle

Answer 15

becoz its two sides are equal dude ;)

Answer 16

it has 2 sides the same

Answer 17

& one side is diffrent

Answer 18

dividing it through the mid point of the 16 side to the angle between the 10 sides gives you two right triangles.

Answer 19

so im multipling 10x10x16 right

Answer 20

Oops sorry isosceles. But you still get the two right triangles.

Answer 21

why ??

Answer 22

which formula r using ??

Answer 23

trying to find s

Answer 24

here,
a=10
b=10
c=16\[s=\frac{10+10+16}{2}\]\[s={{36 \over 2}=18}\]

Answer 25

\[\LARGE{\sqrt{18(18-10)(18-10)(18-16)}}\]now solve :)

Answer 26

@just.chris if can please elaborate on how its right triangle, it would be great, because you would have found much simpler way to find the area.

Answer 27

jiteshmeghwal9 we should do this not in Claire4Christ question unless she is interested in the discussion.

Answer 28

im fine

Answer 29

I don't mind it lol

Answer 30

LOL if he/she is not interested then why did she ask the question ??

Answer 31

@just.chris

Answer 32

324-180+324-180+324-288

Answer 33

Angle bisector theorem. But it makes sense too looking at the attached diagram.

Answer 34

I always try to get everything to right triangles, maybe it is a weakness of mine, but if I can I can do almost everything just by remembering a^2 + b^2 = c^2.

Answer 35

20+20+256

Answer 36

hey hartn, in the last problem we did with teh pulley, so basically dh/dt is the same as dy/dt

Answer 37

, yes one moment

Answer 38

we have a nice formula for isosceles triangle, area , we can use pythagorean theorem

Answer 39

here is a problem very similiar

You can find the height by cutting the triangle in half so that one of the 2 equal sides is the hypotenuse then use Pythagorean's formula:
