We see 2 congruent angles (A and B) that adjacent to the side AB,
this is Angle- Side-Angle Theorem. (A)
For right triangle it can be called Leg-Angle theorem. (F)
It could be Side- Angle- Side theorem, because AB=XY, BC=YZ, angle B=angle Y, but for right triangle it names Leg-Leg theorem. (B)
Answer:
Step-by-step explanation:
441.
You can tell this because the largest area of any rectangle is when it is a square. Even sides will always produce the greatest area. Thus, 21 and 21 would be the best numbers to use.
number of messages she can send and receive so the unlimited plan is cheaper than paying for each message
<em><u>Solution:</u></em>
Natalie can send or receive a text message for $0.15
Natalie can get an unlimited number for $5
To find: Number of messages she can send and receive so the unlimited plan is cheaper than paying for each message
Let "x" be the number of messages
Cost for sending and receiving message = $ 0.15
Cost for unlimited plan = $ 5
Then, according to given, we frame a inequality as:
The condition is: unlimited plan is cheaper than paying for each message
Therefore,
(number of messages)(Cost for sending and receiving message) is greater than or equal to Cost for unlimited plan

Thus for
messages ,the unlimited plan is cheaper than paying for each message
