Using Angle Side Relationship Theorem, use the side measures to list the angle measures of the triangle in order from biggest to smallest.
Q
R
P

Answers

Answer:

∠Q, ∠P, ∠R

From largest to smallest.

Step-by-step explanation:

Remember that the largest side is always opposite from the largest angle.

26 is the longest side. The angle opposite is 26 is ∠Q. So, ∠Q is the largest angle.

21 is the second longest side. ∠P is the angle opposite to 21. So, ∠P is the second largest angle.

Finally, 17 is the shortest side and ∠R is opposite to 17.

So, ∠R is the smallest angle.

Therefore, the measures of the angles from biggest to smallest is:

∠Q, ∠P, ∠R

Answers

Answer:

I'm sorry I haven't read the book in a long time but here are some tips.

Only talk about the events that susan would know about. Don't talk about john at home and things like that.

Make sure you use words that shows Susan is not happy like hate, stupid, etc. Not sure if you are girl or boy, but make sure you talk about all the little details that girls would think about. Like john getting chocolate on Susans dress. You could also talk more about the coin and what she was going to do with it(you can make something up cuz teachers give points for creativity.)

Answers

the first shampoo cost $0.75 per unit. you get this by dividing 6 by 8.
the second shampoo cost $0.80 per unit. which you get by dividing 4 by 5.
The answer will be shampoo one and it has a lower unit rate of 0.05.

Answer:

Shampoo number one has a lower unit rate

It is lower by 10 cents

Step-by-step explanation:

To find the unit rate for bottle one do 6/8 which is 0.75 so for bottle one, one ounce of shampoo cost 75cents

For shampoo two do 4/5 = 0.8 so for every one ounce it costs 80 cents

So shampoo number one has a lower unit rate

and it is 80-70= 10 cents lower
