Hope this helps! Have a great day!
It seems the first line has to be
1. AB=CD and AD=CB 1. given
2. AC=AC 2. Reflexivity (things are equal to themselves)
3

ACB

CAD 3. SSS
4.

1 =

4. Corresponding parts of congruent triangles
5 DC || AB 5. Congruent alternate traversal angles imply parallel lines
I'm guessing you're saying that the sprinkler is shooting out 23 ft of water.
This would be the same as the radius of a circle, and we're trying to find the area. Use the formula.

Plug in what we know:


This is what they could be looking for, an exact value. If they want an approximation, we can input 3.14 for Pi:

A:amount of money invested in the account with 3% simple interest
B: amount of money invested in the account with 4.5% simple interest
a+b=25000 ——>a=25000-b
0.03a+0.045b=900
30a+45b=900000
2a+3b=60000
2(25000-b)+3b=60000
50000-2b+3b=60000
B=10000
A=25000-10000=15000
