Answer:
supplementary angles are two angles that when add equal 180 degrees.
The supplement of an angle is 180 - n.
Step-by-step explanation:
n = 17(180 - n)
n = 3060 - 17n
n + 17n = 3060
18n = 3060
n = 3060/18
n = 170
so the unknown angle (n) = 170 degrees and its supplement = (180 - 170 = 10)......= 10 degrees.
-(7+8/100)
= -(7+4/50)
= -(7+2/25)
= -177/25
20L = 20,000mL. 20,000 / (22+3) people = 800mL/person
