Answer:
See explanation
Step-by-step explanation:
Consider triangles CAX and BAX. In these triangles,
- given
- given
- reflexive property
By SAS postulate, 
Congruent triangles have conruent corresponding parts. So,
Consider triangles CXY and BXY. In these triangles,
- - proven
- given
- reflexive property
By SAS postulate, 
Congruent triangles have conruent corresponding parts. So,
For this case we have:
Cost of manufactures of T-shirts 
where x represents the number of T-shirts
Part A:
Substituting 
in the total cost equation you have to:
Thus, the cost of 8 shirts will be 
Part B:
If 
then
Thus, the cost of 12 shirts will be 
Answer:
complementary angles = 90
2x-5 + 5x+4 = 90
combine like terms
7x-1 =90
7x = 91
divide by 7
x =13
angle a
2x-5
2*13-5
26-5
21
Angle a: 21
Given :
7x is an odd integer.
To Find :
The next odd integer as an algebraic expression in x.
Solution :
All positive integers are :
1 , 2 , 3 , 4 , 5 , ......
From the above series we noticed that every other odd number is 2 more than the previous one.
So , 7x is an odd number.
Therefore, next odd number is 7x + 2.
Hence, this is the required solution.
