By which rule are these triangles congruent? a) aas b) asa c) sas d) sss

SSS

Step-by-step explanation:

SSS (side-side-side) because you see those red lines on each line? >that means that they're equal. so xy = zy and xw = zw and wy = wy so yeah SSS

SSS

Step-by-step explanation:

Side Side Side because:

WY=WY because of the reflexive property

YX= YZ because it is given in the diagram

XW=ZW because it is given in the diagram

i think this could be a possible answer (1 / 84) -1

good luck! : d

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
