Answer:
The measure of one angle of a regular convex 20-gon is 162°
Step-by-step explanation:
* Lets explain how to solve the problem
- A convex polygon is a polygon with all the measures of its interior
  angles less than 180°
- In any polygon the number of its angles equal the number of its sides
- A regular polygon is a polygon that is all angles are equal in measure
  and all sides are equal in length
- The rule of the measure of an angle of a regular polygon is
   , where m is the measure of each interior
, where m is the measure of each interior
  angle in the polygon and n is the numbers of the sides or the angles 
  of the polygon
* Lets solve the problem
- The polygon is convex polygon of 20 sides (20 angles)
- The polygon is regular polygon
∵ The number of the sides of the polygon is 20 sides
∴ n = 20
∵ The polygon is regular
∴ All angles are equal in measures
 
∵ The measure of each angle is 
∴  
 
∴ 
∴ 
∴ m = 162
∴ The measure of one angle of a regular convex 20-gon is 162°

Step-by-step explanation:
To find 60% of people you just multiply .6 with the number you are trying to find 60% of. Like 100. 100 times .6 = 60.
 
        
                    
             
        
        
        
the first step Andre made was 
 2x+6=3x-8
 or, -x+6=-8
 And the first step Diego made was 
 2x+6=3x-8
 or, +6=3x-2x
 or, 6=x-8
...
 
        
             
        
        
        
Answer:
see the formula in book
Step-by-step explanation:
change the first 2 brackets into cos sin like that
then after,change both into another formula
sin theta plus cos theta will come ans
