Question

In square MNKJ, diagonal MK measures square root 50 and in rectangle IJKL, diagonal KI measures 13. What is the length of IJ or KL?

Answer 1

picture with problem

Answer 2

12

Answer 3

how is it 12??
Can you just show me how you got the answer??

Answer 4

in the square, triangle mkj is right angle triangle.
pythagoras theorem tells us that MJ^2+JK^2 = MK^2
but we know that MJ = JK, since MNJK is a square.
so 2JK^2 =MK^2
we know that MK^2 = 50
so JK = 5

Answer 5

again, in the rectangle IJKL, IJK is a right angle triangle. you know IK and JK, find IJ

Answer 6

MK^2= square root 50.....not 50

Answer 7

no. read the question. MK measures sqrt 50
so MK^2 = 50

Answer 8

so IJ is 12?

Answer 9

yes

Answer 10

thanks :)
