Answer:
P = 6 units
 units
A = 38 sq units
Step-by-step explanation:
P = 2 + 2
 + 2 + 1
 + 1 + 1
 + 1 
 
P = 6 
 
A = 2 ·
 ·  
  
A = 2 (19)
A = 38 sq units
 
        
             
        
        
        
Answer:
118°
Step-by-step explanation:
because 28 + 90 = 118
 
        
             
        
        
        
Answer: B
Step-by-step explanation:
Since this is a 30-60-90 triangle, b=8(sqrt3) = 8sqrt3.
By the same logic, c=8(2)=16.
 
        
             
        
        
        
This is from simple math knowledge of lines, segments and points. From the given data, pr and rs are line segments in the line ps. Thus, we add segments pr and rs together to solve for the line ps. 
pr + rs = ps
4x - 2 + 3x - 5 
(Add like terms) = 7x -7
(Further simplify) = 7(x-1)
Therefore, the final answer or expression of ps = 7(x-1).
        
                    
             
        
        
        
Area for a triangle is (1/2) bh or bh/2
So using this info, b = 1.5 m and h = x and A = 1.5 m^2
A = bh/2
1.5 = 1.5x/2
Multiply both sides by 2 to get rid of fraction ... 3 = 1.5x
Divide both sides by 1.5 ... 2 = x so x= 1.5 m
