Answer:
x = 30°
Step-by-step explanation:
5x + x + x + 5x = 360° ( exterior angle property)
12x = 360°
x = 360/12
x = 30°
 
        
             
        
        
        
Answer:
T = m + 500

I would assume this question is asking for the sum of the two values. Sorry if this isn't helpful. (T means total btw)
 
        
             
        
        
        
In each graph, they give you a line.
For part A, they want you to use the <u>Distance Formula</u> which is:

(x2 is supposed to be x sub 2, but I can't put subheadings in the equation tool)
x1, x2, y1, and y2 are the coordinates of the endpoints of the segment.
For part B, they want you to use the <u>Midpoint Formula</u>, which is:

The coordinate pair you get from the Midpoint Formula is your midpoint.
Hope this helps! :)
