Answer is 49.2
Total of all angles = 360
(x+16) + (x) + ( 6x-4) + (2x+16) = 360
10x + 28 = 360
X= 33.2
Angle A = x+16= 33.2+16= 49.2
 
        
             
        
        
        
Answer:
Given:  , y =6
 , y =6
To prove: x =7
On substituting the value of y =6 in the equation 7y = 8x -14 to solve for x.
 
 
or
42 = 8x -14                       ......[1]
Addition Property of equality states that you add the same number to both sides of an equation.
Add 14 to both sides in equation [1];
42+14 =8x -14+14
Simplify:
56 = 8x               
or
8x =56                                 ......[2]
Division Property of equality states that you divide the same number to both sides of an equation.
Divide by 8 to both sides of an equation [2];

Simplify:
x =7                             Hence proved!
A two Column proof:
   Statement                                  Reason
1. 7y = 8x -14                                   Given
     y= 6
2. 7(6) = 8x -14                                Substitution property
3.  42+14 = 8x                                  Addition property of equality
4.   56 =8x                                       Simplify
5.    x =7                                           Division Property of equality
 
        
                    
             
        
        
        
Answer:
90
Step-by-step explanation:
an obtuse angle is an angle from 90 - 180 degrees, so it would greater than 90 degrees
 
        
             
        
        
        
Answer:
75
Step-by-step explanation:
<h2>A=1/2h(a+b)</h2><h3> =10÷2=5(10+5)</h3>
 =5×15
<h2> =75</h2>
