In ΔAOD  (AD)  =(AO) 
2+(OD) 
2   =36+64    AD 
2 =100
   AD= 100
 =10cm
  Rhombus has all sides equal
AB = AD = BC = CD = 10 cm 
 
        
             
        
        
        
First, change the fractions to a common denominator, which is 21. 
so 3/7 * 3/3  = 9/21
1/3 * 7/7 = 7/21
Add the two together
9/21 + 7/21 = 16/21
Then take 21/21 - 16/21 = 5/21
There is 5/21 of the pizza left.

Answer:
90
Step-by-step explanation:
Angle Formed Outside = 1/2(DIFFERENCE of Intercepted Arcs)
ARC LN = 360 - 270 =90
LMN  = 1/2(270 -90)
          = 1/2 (180)
         = 90
