List the sides of each triangle from shortest to greatest
Lelechka [254]
In every triangle, the largest side, is opposite the largest angle.

Also, the smallest side, is opposite the smallest angle.


a.70^o\ \textgreater \ 60^o\ \textgreater \ 50^o so |RQ|\ \textgreater \ |PR|\ \textgreater \ |PQ|, 

because RQ is opposite angle P, the largest,
PR is opposite angle Q , the middle
and PQ is opposite angle R, the smallest.

Greatest side: RQ


b. The sum of the measures of the interior angles of any triangle is 180°, 

so 

m(A)+m(B)+m(C)=180^o\\\\50^o+45^o+x=180^o\\\\x=180^o-50^o-45^o=85^o

thus, m(C) is the largest angle. This means the largest side is the side AB.



Answers:

a) RQ
b)AB

a rectangular cake has a length of 15 inches and a width of 10 inches how many whole square pieceslenghts of 2 1/2 inches can be
sineoko [7]

Answer:

24

Step-by-step explanation:

The cake measures 10 inches by 15 inches. If pieces are 2.5 inches long and wide (they are square and equal) then 6 pieces will be cut along the length.

15/ 2.5 = 6

And 4 pieces will be cut along the width.

10/ 2.5 = 4

All together when the entire cake is cut, there will be 4*6 = 24 squares 2.5 inch long pieces.

A concession stand sold pizza slices, ice cream cones, and tacos at a basketball game. Pizza slices were sold for $2.75, ice cre
Ray Of Light [21]

Answer/Step-by-step explanation:

What we already know:

Pizza slices $2.75 - Ice cream cones $2.25 - Tacos $1.75

Total Items sold - 121 / Total amount of money - $260.75/ <u>$87.50 made from selling Tacos</u>

<u>____________________________________</u>

Tacos - 87.5 ÷ 1.75 = 50 Tacos sold -- 121 - 50 = 71 items

& 260.75 - 87.5 = 173.25 left

____________________________________

You can't sell half an Ice-Cream

Ice Cream - 71 - 1 = 70 -- 70 ÷ 2 = 35 -- 35 × 2.25 =

<h3>$78.75 made from Ice-cream cones</h3><h3>35 Ice- cream cones sold</h3><h3>**************************************************</h3>

Pizza slices - 71 - 70 = 1 -- 1 + 35 =

<u>36 Pizza slices sold</u>

36 × 2.75 =

<u>99 dollars made off of Pizza slices</u>

**I dont know if this is correct**
