Answer:
Step-by-step explanation:
By triangle sum theorem, 
Sum of all angles of a triangle is 180°.
m∠1 + m∠2 + m∠3 = 180°
(m∠1 + m∠3) + m∠2 = 180°
2(m∠1) + 70° = 180° {Given → m∠1 = m∠3]
2(m∠1) = 110°
m∠1 = 55°
Therefore, m∠1 = m∠3 = 55° 
 
        
             
        
        
        
Answer:
it is 13x=2
Step-by-step explanation:
i ran the math through my multipurpose calculator
 
        
                    
             
        
        
        
N= a number
2n= twice a number
If it's 43 less, then it would be 2n-43.
2n-43 is the answer.
Hope this helps!  :)
        
                    
             
        
        
        
neither
• Parallel lines have equal slopes
• The product of perpendicular slopes = - 1
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y =  x + 3 is in this form
 x + 3 is in this form
with slope m = 
rearrange 20x + 12y = 12 into this form
subtract 20x from both sides
12y = - 20x + 12 ( divide all terms by 12 )
y = -  + 1 ← in slope-intercept form
 + 1 ← in slope-intercept form
with slope m = - 
Neither of the conditions for parallel/ perpendicular slopes are met
Hence the lines are neither parallel/ perpendicular
 
        
             
        
        
        
We know 





Now
- New Radius=2(4)=8cm
- New Height=2(8)=16cm




So 



Hence our correct option is Option C
