Question 208310
    the means of two complementary angles are 16z-9 and 4z+3.find the measures of the angles
.
If two angles are "complementary", the sum of the two angles MUST equal 90 degrees.
.
(16z-9) + (4z+3) = 90
16z-9 + 4z+3 = 90
16z+4z+3-9 = 90
20z-6 = 90
20z = 96
z = 96/20
z = 24/5
.
Therefore, the two angles are:
16z-9 = 16(24/5)-9 = 16(4.8)-9 = 76.8-9 = 67.8 degrees
4z+3 = 4(24/5)+3 = 4(4.8)+3 =  19.2+3 = 22.2 degrees
