We know that
<span>Since a circle is 360 degrees, 
then 
360</span>°-----------> 100%
<span>x </span>°----------> <span>15% 
</span>x=15*360/100-----> x=54°
the answer is
54 degrees
        
                    
             
        
        
        
Answer:
20 square inches
Step-by-step explanation:
Set width of sign to x.
Set length of sign to y.
5x=y
2(x+y)=24 inches
2(x+5x)=24 inches
12x=24 inches
width = 2 inches
length = 10 inches
Area = 20 square inches

<em>To convert decimal number 1</em><em>2</em><em>3</em><em> to quinary, follow these steps:</em>
<em>1</em><em>.</em><em> </em><em>Divide 1</em><em>2</em><em>3</em><em> </em><em>by 5 keeping notice of the quotient and the remainder.</em>
<em>2</em><em>.</em><em>Continue dividing the quotient by 5 until you get a quotient of zero.</em>
<em>3</em><em>.</em><em> </em><em>Then just write out the remainders in the reverse order to get quinary equivalent of decimal number 1</em><em>2</em><em>3</em><em>.</em>
 
        
             
        
        
        
Answer:
   Dimensions of original room = 12 x 12 feet.
Explanation:
  Let the size of old square room be a x a.
  New dimension = ( a+4 ) x ( a + 6 )
    We have area of the new room will be 144 square feet greater than the area of the original room.
   So,     ( a+4 ) x ( a + 6 ) = a x a + 144
               a²+10a+24= a²+144
               10a = 120
                   a = 12 feet.
  Dimensions of original room = 12 x 12 feet.
