Answer:
72
Step-by-step explanation:
you take the two 54's and add them together and get 108 then you take 108 and subtract it from 180 because that's what the angles of all triangles add to and you get 72
 
        
                    
             
        
        
        
1) answer is D.
<1 = 53
2)
53 x 4 = 212
360 - 212 = 148
<2 = 148/4 = 37
answer is C.
<2 = 37
        
             
        
        
        
Answer:
A  yes     B No    C  Yes
Step-by-step explanation:
The length of the third side is greater than the difference and less than the sum of the two smallest sides.
8, 5, 7    Using the 5 and 7  the third side is > (7 - 5) and < (5 + 7)
                                               the third side is  > 2  and < 12 so 8 is OK
 10, 3, 7   Use the two smallest number: 3 and 7 
                                                the third side is  > (7 - 3) and < (3 + 7)    
                                                the third side is > 4 and < 10   No it is 10 
 9, 5, 15    Use the two smallest number 9, 5
                                                the third side is > (9 - 5) and < (9 + 5)  
                                                the third side is > 4 and < 14       Yes  
 
        
             
        
        
        
This statement is false. The value of r does not represent the reference angle when plotting a point in the polar coordinates. In fact, r represents the distance of an angle because the theta is the one who gets to represent the reference angle.
