The value of x or the length of the MJ is 4.9 units after using the similarity property.
What is the similarity law?
It is defined as the law to prove that the two figures have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
We have two figures shown in the picture.
The two figures are similar.
By using the similarity property:
4/2.8 = 7/x
After solving:
x = 4.9
or
MJ = 4.9
Thus, the value of x or the length of the MJ is 4.9 units after using the similarity property.
