Answer:
![\angle A=17\textdegree](https://tex.z-dn.net/?f=%5Cangle%20A%3D17%5Ctextdegree)
Step-by-step explanation:
We know that A and B are complementary angles. So, they must add up to 90°. As an equation:
![\angle A+\angle B=90](https://tex.z-dn.net/?f=%5Cangle%20A%2B%5Cangle%20B%3D90)
Since we know their equations, substitute:
![(x+8)+(8x+1)=90](https://tex.z-dn.net/?f=%28x%2B8%29%2B%288x%2B1%29%3D90)
Solve for x. Combine like terms on the left:
![9x+9=90](https://tex.z-dn.net/?f=9x%2B9%3D90)
Subtract 9 from both sides:
![9x=81](https://tex.z-dn.net/?f=9x%3D81)
Divide both sides by 9:
![x=9](https://tex.z-dn.net/?f=x%3D9)
So, the value of x is 9.
We want to find A. So, let's use the equation for A:
![\angle A=x+8](https://tex.z-dn.net/?f=%5Cangle%20A%3Dx%2B8)
Substitute 9 for x:
![\angle A=9+8](https://tex.z-dn.net/?f=%5Cangle%20A%3D9%2B8)
Add:
![\angle A=17\textdegree](https://tex.z-dn.net/?f=%5Cangle%20A%3D17%5Ctextdegree)
So, the measure of A is 17°.
Answer:
A. 3.25x + 13.50 ≤ 40
The number of bracelets is x. It's a variable.
The 13.50 is a constant.
The total needs to be less than or equal to 40 because that's all the money he has.
