A kite has diagonals of 18 inches and 21 inches as seen below. What is the perimeter of the kite?
first you have to find the hypotenuse of both triangles
12?
and 9?
you have to use this formula c^2=a^2+b^2
I know that part :b
ok plug the a and b in and the you will find c :)
theres two triangles in the kite so for the first on the a=9 and b=9 for the second one the a=9 and the b=12
after you find the c for both triangles you will have the side lengths
I already did that and got 225 and got the square root of 15.
I mean sqrt of 225 which =15
show me wht you did for the little triangle with a=9 and b==9
I don't know what you mean D; I'm just trying to find the perimeter
lol you need the hypotenuse to know the perimeter
its 15
the hypotenuse=15
9^2+9^2=162 -.- and 162 sqaure rooted is 12.7
so the hypotenuse is 12.7? what about the 12? don't you need 12 to find the hypotenuse?
then for the other triangles hypotenuse its goin to be 9^2+12^2 which equals 225 and 225 sqaure rooted is 15
so now you have the side measurements you can round 12.7 to 13
so its 13+15+13+15
thats your perimeter
where does the 13 come from, you round up?
yes i rounded 12.7 to 13
so its 56 or 55.4 without rounding the 12.7
hoped this helped :)
yes so much !!!!! thankyouuuuu!!!!!!!!! :))))))))
your welcome ^.^ :D :)
