Question

The measures of 2 complementary angles are 16z-9 and 4z+3. find the measures of these angles.

Answer 1

Add them together and make them equal to 90 degrees

Answer 2

16z-9+4z+3=90
16z+4z=96
20z+96
z=4.8

Answer 3

16z-9+4z+3=90
20z-6=90
20z=96
z=96/20
z=24/5
z=4.8

Answer 4

Complementary means they add up to 90 degrees
Supplementary means they add up to 180 degrees

A good way to remember that is "C" comes before "S" in the alphabet and 90 comes before 180.

Answer 5

Z=4.8
