Answer:
Im pretty sure its 45 degrees
Step-by-step explanation:
Its an isosceles triangle so the upper 2 angles are Equal and a triangles angles adds up to 180 degrees, so if we have a 90 degree angle (the square) there's only 90 degrees left, so if you divide the 90 degrees by the remaining 2 Equal angles you get 45.
 
        
             
        
        
        
Answer:
Lets a,b be elements of G. since G/K is abelian, then there exists k ∈ K such that ab * k = ba (because the class of ab, ![[ab]_K](https://tex.z-dn.net/?f=%20%5Bab%5D_K%20) is equal to
 is equal to ![[ba]_K](https://tex.z-dn.net/?f=%20%5Bba%5D_K%20) , thus ab and ba are equal or you can obtain one from the other by multiplying by an element of K.
, thus ab and ba are equal or you can obtain one from the other by multiplying by an element of K. 
Since K is a subgroup of H, then k ∈ H. This means that you can obtain ba from ab by multiplying by an element of H, k. Thus, ![[ab]_H = [ba]_H](https://tex.z-dn.net/?f=%20%5Bab%5D_H%20%3D%20%5Bba%5D_H%20) . Since a and b were generic elements of H, then H/G is abelian.
 . Since a and b were generic elements of H, then H/G is abelian.

Answer:
 The cost of the 1 muffin is $1.5 and 1 quart of milk cost is $3 .
Step-by-step explanation:
Let us assume that the cost of one muffins be x.
Let us assume that the cost of one 1 quarts of milk be y.
As given
The cost of 8 muffins and 2 quarts of mil is $18.
Than the equation becomes
8x + 2y = 18 
As given
The cost of 3 muffins and 1 quart of milk is $7.50.
Than the equation becomes
3x + 1y = 7.50 
Two equations are
8x + 2y = 18  and 3x + 1y = 7.50 
Multiply  3x + 1y = 7.50 by 2 and subtracted from 8x + 2y = 18 .
Thus
8x - 6x + 2y - 2y = 18 - 15
 2x  =  3

x = 1.5 
Put x = 1.5 in 3x + 1y = 7.50 
3 × 1.5 + y = 7.50
y = 7.50 - 4.5
y = 3
Therefore the cost of the 1 muffin is $1.5 and 1 quart of milk cost is $3 .
