The two angles are complementary, so they must add to 90 degrees (by definition)
(Angle 1) + (Angle 2) = 90
(16z - 9) + ( 4z + 3 ) = 90
16z - 9 + 4z + 3 = 90
20z - 6 = 90
20z = 90+6
20z = 96
z = 96/20
z = 4.8
Now plug this back into the two original angle expressions
---------------------
Angle 1 = 16z - 9
Angle 1 = 16*4.8 - 9
Angle 1 = 67.8 degrees
---------------------
Angle 2 = 4z + 3
Angle 2 = 4*4.8 + 3
Angle 2 = 22.2 degrees
