x = 540° -480°
x = 60°
Is that all the question says? If not, please say what else it says.
Given
ZY=3XY
Prove that
ZX =4XY
To proof
As given
ZY=3XY
as shown in the diagram given in the question
we get
XZ = XY + YZ
As given in the question
ZY=3XY
put this in the above equation
we get
XZ = XY + 3XY
XZ = 4XY
Hence proved
