HIJK IS A RECTANGLE. FIND THE VALUE OF X AND THE LENGTH OF EACH DIAGONAL

OpenStudy (anonymous):

HJ= x and IK = 2x-7

OpenStudy (anonymous):

Do you know that diagonals of a rectangle are equal?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

Oh ok do you know pythagoras theorem?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

i just need a simple brief explanation of how you do it

OpenStudy (anonymous):

i have the answers.

OpenStudy (anonymous):

Ok so diagonals of a rectangle are equal so x=2x-7 x=7.

OpenStudy (anonymous):

x=7, HJ= 13 IK=13 Is the answer. but how.

OpenStudy (anonymous):

Diagonals of a rectangle are equal the diagonals are HJ and IK so they are equal. so x=2x-7.

OpenStudy (anonymous):

now what

OpenStudy (anonymous):

how do i get HJ AND IK

OpenStudy (anonymous):

you know x=2x-7 so x=7 now one length is 7 and the other length 2x-7=2*7-7=7.

OpenStudy (anonymous):

HJ= 13 IK=13

OpenStudy (anonymous):

IS THE ANSWER. HOW DO I GET IT

OpenStudy (anonymous):

Then the answer is wrong or you have typed the conditions wrong....

OpenStudy (anonymous):

No its right

OpenStudy (anonymous):

i'm sorry, you're right
