First choose 1 equation and set it equal to 180 because supplementary angles equal up to 180 degrees.
12q - 9 =180
Now solve for q.
12q - 9 +9 = 180 + 9
12q = 189
12q/12 = 18912
q = 15.75
now subtract 15.75 from 180
180.00 - 15.75 = 164.25
Your angles equal to 164.25 and 15.75 degrees.

Answer: A
Step-by-step explanation:
it all refelects over the x=6
Answer:
x = -25 / 3
Step-by-step explanation:
10 / 3 = x / (-5/2)
10 / 3 * (-5 / 2) = x
x = -50 / 6
x = -25 / 3
