Ten times the sum of two and five tenths and thirteen and 5 tenths.
        
                    
             
        
        
        
B, make a table of possible values
the best way to do it is actually not listed
to have max area with minimu perimiter, try to get the sides as close measure to each other as possible
I would pick B though
        
             
        
        
        
Answer:
1st ∡ = 15.5° 
2nd ∡ = 77.25° 
3rd ∡ = 87.25° 
Step-by-step explanation:
1st ∡:  x
2nd ∡:  y
3rd ∡:  z
Equations we can create from data given in problem:
y + z = 5x
z = 5x + 10
We have enough expressions to create an equation:
x + 5x + 5x + 10 = 180
11x = 170
x = 15.5
y = 5(15.5) = 77.25
z = y + 10 = 87.25

Answer:
x = 165, y = 15
Step-by-step explanation:
1. Well, what does supplementary mean? - The angles add up to 180°. 
2. Let's form an equation: x + y = 180°
3. Let's say x is the larger angle and y is the smaller angle. 
4. Let's form another equation: x = 150 + y
5. Put the two equations next to each other: 
x + y = 180
x = 150 + y
6. We know what x is equaled to, so let's plug it into the first equation!
150 + y + y = 180
150 + 2y = 180
-150           -150
2y = 30
y = 15
7. Now, we know what y is, let's find x!
x + 15 = 180
    -15     -15
x = 165
