Answer:
Rotation 180° counterclockwise about the origin
 
        
                    
             
        
        
        
Step-by-step explanation:
(5,2) & (10,-3) 
the slope of the points are 
y2 - y1 / x2- x1 
-3-2/10-5 
-5/5 
-1 
the mid point of the given points are
x= x1 + x2/2 , y= y1 +y2 /2 
.
.
.
.
( , )
the equation of the line that passes through the given points are as 
y+ y1 = m (x+ x1) 
:. now put the value of the mid point in y1 and x1 and the value of slope in m 
also find the mid point, it's hard to do it in a mobile without calculator and paper and pen

The answer is B 
Solution: 
Find perimeter (L+B+L+B) 
600+300+600+300= 1,800
1,800/3= 600
600x500= 300,000
        
                    
             
        
        
        
Answer:
11x+16

Answer:
Missing side=25 units.
Area of the figure= 470 sq units.
Step-by-step explanation:
The figure is made up of a rectangle and a triangle.
To get the base of the triangle, we find the difference between the two parallel sides, that is, 16ft and 31 ft.
31ft-16ft=15ft  
The height of the triangle is 20 since it is parallel and equal to the length of the rectangle.
We therefore use pythagoras theorem to find ?
a²+b²=c²
15²+20²=c²
625=c²
c=25
ii. The figure is a trapezium therefore we use the following formula to find the area.
A= 1/2(a+b)h, where a and b are the two parallel sides. and h the distance between them.
=(1/2)(31+16)×20
=470 sq units
