obtuse because it all adds up to 180 degrees
Answer:
yes
Step-by-step explanation:
This is a problem where you should make an equation.
Let's say x is the first week. It would mean
First Week : x
Second Week : x + 5
Third Week : 2(x+5)
You need to add these up to make your equation. Your equation will look something like this :
![x+x+5+2(x+5) = 431](https://tex.z-dn.net/?f=x%2Bx%2B5%2B2%28x%2B5%29%20%3D%20431)
Now you simplify.
![2x+5+2x+10 = 431](https://tex.z-dn.net/?f=2x%2B5%2B2x%2B10%20%3D%20431)
![4x+15 = 431](https://tex.z-dn.net/?f=4x%2B15%20%3D%20431)
![4x = 416](https://tex.z-dn.net/?f=4x%20%3D%20416)
That means they sold 104 Boxes in the First Week.
So they sold 109 Boxes the Second Week.
109 x 2 = 218
And they sold 218 Boxes the Third Week.

Answer:
337.406388 or 337 people
Step-by-step explanation:
To figure this out, use the compound interest (compounding number?) equation which is Amount = People(1 + rate)^time
So if you fill that out you get
A = 20,000(.96)^100
A = 20,000(0.0168703194)
A = 337.406388
B. complementary because 126+54= 180°
