The pairs of angles that have equal measures are:
- LJP
- NJR
- MJP
- PJR
The pairs of angles that do not have equal measures are:
- MJK
- PJR
- KJR
- MJP
- KJL
- LJM
When two lines or rays converge at the same point, the measurement between them is called a "Angle."
It is given that:
Both MJK and PJR can be seen as (Unequal angles)
The angle MJK is ( 90 degrees), then angle PJR will be ( 48 + 46 )= 94 degrees
Both LJP and NJR can be seen as ( Equal angles)
The measure of angle LJP = 48 + 46 + 48 = 142 degrees
The measure of angle NJR = 48 + 48 + 46 = 142 degrees
KJR & MJP = Unequal
The angle KJR will now be [ 360 - (46+48+48+46+90) ]
= 82 degrees
The angle MJP will be ( 94 degrees)
Both KJL & LJM are Unequal, then
The angle KJL will be 42 degrees, then angle LJM will be ( 90 - 42 )
= 48 degrees

Step-by-step explanation:
Look at the picture.
ΔADC and ΔCDB are similar. Therefore the sides are in proportion:
We have
Substitute:
