Answer:
144&36
126&54
21&159
Step-by-step explanation:
Supplementary means angles that add up to 180 degrees
Since these angles add up to 180 degrees, they are therefore supplementary
Answer:
d
Step-by-step explanation:
its d because square has equal sides, so the midpoints would also be all equal sides, which is the definition of a square
Answer:
twenty thousand four hundred and eight four one hundred and sixty four
3x-3 and 4x-6 are complementary angles meaning together they add up to 180°. Set them equal to each other. So you get 3x-3=4x-6 now simplify this. Now you have x=3 and there you have it! If you plug 3 into x in both equations it works! Hope this helps!
Since if he gets the driveway done in 20 minutes he gets 1/20th of the driveway done in 1 minute (if x=20 then x/20=1 by dividing both sides by 20) and if his brother gets 1/12th of the driveway done in one minute, then if t represents the time it takes to shovel the driveway, t/20+t/12=1 driveway shoveled as 1/20+1/12=amount they can do in 1 minute, so t/20+t/12 is how much they can do in t minutes. Multiplying both sides by 20*12=240, we get 12t+20t=32t=240. Dividing both sides by 32, we get 240/32=7.5 minutes to shovel the driveway.
