4x 3x -8
angle ADJ is a right angle, so it is equal to 90 degrees. so if you added the two missing numbers together (4x and 3x-8) it would have to equal 90.
4x+3x-8=90
7x-8=90
7x=98
x=14.
plug x back into the equations to find your angles.
3(14)-8 and 4(14)

4x+(3x-8)=90

4x+3x-8=90

7x=98

x=98/7

x=14

If x=14,

angle CDJ is:

(3(14)-8) degrees

=34 degrees
