Supplementary angles add up to 180° → supplementary to 30° is 180° - 30° = 150°. Complementary angles add up to 90° → complementary to 30° is 90° - 30° = 60°.
21/30 + 8/30 = 29/30

The answer is: 20/2 plus 30 = 40
factors of 30 that add to 17 are 2 and 15
13 add something equals 30 = 43
The correct answer is: 1000+40+1000+30+1000+20+1000+10 = 4100

Supplementary angles add up to 180° → supplementary to 30° is 180° - 30° = 150°. Complementary angles add up to 90° → complementary to 30° is 90° - 30° = 60°.
It is impossible for three prime numbers less than 30 to add up to 1955. After all, 30+30+30 is only 90.
10%+30%=40%
1000 + 1000 + 1000 + 1000 + 40 + 30 + 20 + 10 = 4100
21/30 + 8/30 = 29/30

-30 and -30 -30 + -30 = -60 -30 x -30 = 900
