Question

if x- y-z and l(x,z)= 7√2, l(X,Y)=3√2, then l(Y,Z) =???​

Answer 1

Answer = I(YZ)=2√7

Explanation:

I(XY) + (YZ)

3√7= √7 + I(YZ)

I(YZ) = 3√7 - √7

= √7(3-1)

=√7(2)

I(YZ) = 2√7

Answer 2

Explanation:

We have, l(XZ)=37;l(XY)= 77

Now, l(XZ)=l(XY)+l(YZ)

So, l(YZ)=l(XZ)−l(XY)=3

7− 7

∴l(YZ)=27
