Supplementary Angles
Hey guys,
I answered these questions and I was wondering if they are correct
16-C
16. 68, 86
A 45
B 56
C 26
D 19
E 32
F 82
17- F
17. 55, 77
A 18
B 37
C 62
D 57
E 20
F 48
18-A
18. a, (a + 80)
A 100 - 2a
B 112 - 7a
C 182 - 2a
D 254 - 5a
E 311 - 3a
F 302 - 1a
19-D
19. x, (x + 20)
A 189 - 7x
B 167 - 1x
C 114 - 5x
D 160 - 2x
E 124 - 2x
F 142 - 1x
20-A but am really stuck and confused on this one
20. m, 2m
A 172 - 2m
B 187 - 7m
C 124 - 4m
D 143 - 1m
E 164 - 9m
F 180 - 3m
One, who adopts patience, will never be deprived of success though it may take a long time to reach him. Imam ali (as)<3
so wouldn't be m+2m=180#3 2012-09-21 07:04:18

Re: Supplementary Angles
Hi zee-f;
Now solve for c.
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: Supplementary Angles
Hi zee-f!
In all these problems you are to find the supplement to the sum of the two given angles I assume.
That would be in all these cases 180 - (sum of the two angles).
Eg. 16) 180-(68+86) = 180-154 = 26.
20) 180-(m+2m) = 180-3m.
Be blessed! 
Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).
LaTex is like painting on many strips of paper and then stacking them to see what picture they make.

Re: Supplementary Angles
Hi zee-f;
so the answer would be F
Yep!
