Answer: 87.95
Step-by-step explanation: 10.3% of 853.93
10.3%= 0.103 
So you would do 0.103 times 853.93=87.95479 round that to 2 Dp. You get 87.95
 
        
             
        
        
        
Answer:
There are 7 sides.
Step-by-step explanation:
Let's Use the formula that states that the sum of the angles of an n-sided polygon is given by.
S=(n−2)180 
Since we are given that the two angles are right, the angles and each of the remaining angles is 144.
And Therefore, the sum is:
S=90 
(n−2)144 
(n−2)180 
=90 
+90 
+(n−2)144 
⇒(n−2)180 
−(n−2)144 
=180 
⇒(n−2)(180 
 −144 
 )=180 
⇒(n−2)(36 
=180 
⇒n−2= 
36
180
⇒n−2=5
⇒n=5+2=7
Hence, the polygon has 7 sides.
