The value of gj is 32 units.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Given:
line gh is congruent to line jk i.e., they are equal in length
So, we can write
gh=jk
Also,
gh = x+10, HJ=8, jk=2x-4
So,
x+10=2x-4
10+4=2x-x
14=x
So,
gj= gh + hj
=x+10+8
=14+10+8
= 32
Hence, the value of gj is 32 units.
