The answer would be D i think because if the two angles are to equal 72, and one of the angles equals 42, 72-42= 30. to find x, you’d do 30/6 which equals 5. so x=5 and the angle measure would be 30
 
        
             
        
        
        
Answer:
64°
Step-by-step explanation:
<em>So supplement angles are equal to 180, so first our two angles added together will be 180:</em>
x + x = 180
<em>Now one of these angles is 6 greater than half:</em>
x + (x/2 + 6) = 180
<em>Then we will solve for x:</em>
x + (x/2 + 6) = 180
x + x/2 + 6 = 180
x + x/2 = 174
  x = 174
x = 174
x = 116
<em>Plug it back in:</em>
x + (x/2 + 6) = 180
          /\
      x/2 + 6
    (116)/2 + 6
         64
<em>To check:</em>
116 + 64 = 180 ✓

Answer:
The last one   5x-3y=15   This is the same as  y= (5/3)x -5
Step-by-step explanation:
 5x-3y=15
Move 5x to the right (becoming negative)
-3y = -5x +15
Divide everything by - 3
y= (5/3)x -5
   
y intersect= -5   ( line crosses y coordinate at -5)
Slope = 5/3      From -5  you start counting  (5 up,3 right,5 up,3 right....  OR    5 down,3 left,5 down,3 left........)
 
        
             
        
        
        
Answer:
center = (3, 0)
radius = 2
Step-by-step explanation:
Standard equation of a circle:  
(where (h, k) is the center of the circle and r is the radius)
Given equation:

Rewrite in standard form:

Therefore
- center = (3, 0)
- radius = 2
