= 1/2 + - 8z + -6

Combine Like Terms:

= 1/2 + -6

= (- 8z) + (1/2 + -6)

=(- 8z) + (1/2 + -6)

= - 8z + -11/2

Answer:

Smaller=18 degrees; larger= 162 degrees

Step-by-step explanation:

ok so first supplementary angles mean that the two angles added together will equal 180 degrees.

so 1x + 9x = 180 (combine like terms)

10x=180 (divide each side by 10)

x=18

so the smaller angle is 18 because its only 1x, and the larger angle is 162 because 18x9=162

check: 18 + 162 = 180
