75 degrees because 42+63=105
180-105=x
31 dozen cookies = 372 cookies
372 cookies = 13 cups of flour
1 cookie = 13 ÷ 372 = 0.0349462365591 cups of flour
6 dozen cookies = 72 cookies
72 cookies = 0.0349462365591 x 72 = 2.516 cups
≈ 2.5 cups (nearest 1/4 of a cup)
<h2><u>Direct answer</u> :</h2><h2>

- Segment AO = Segment KT
- Segment OR = Segment TE
- ∠AOR = ∠KTE
- △AOR≅△KTE

- It is given.
- It is given.
- It is given.
- Since two sides and one incised angle is equal in both the triangles we can conclude that they are congruent under the SAS congruence criterion.
<h3>Steps to derive these statements and resons :</h3>
Given :
In triangle AOR and triangle KTE :
- Segment AO = Segment KT
- Segment OR = Segment TE
- ∠AOR = ∠KTE
Since two sides and one included angle of these two triangles are equal, we can conclude that these triangles are congruent under the SAS congruence criterion.
Adjacent means angles are near together & make 180° angel
You find how y and x change and then divide y/x to get your rate of change
