Answer:
   x = 63°
Step-by-step explanation:
~ They are adjacent angles because they have a common (one) vertex.
~ To find the value of x we must make an equation.
Angles on a straight line add up to 180°.
   117 + x = 180
   x = 180 - 117
   x = <u>63°</u>
 
        
             
        
        
        
Answer:
The polynomial is a quadratic binomial
Step-by-step explanation:
we have

Classify the polynomial
<u>By the number of terms</u>
we know that
A polynomial with two terms is a binomial
<u>By the Degree of a Polynomial</u>
we know that
The degree of a polynomial is calculated by finding the largest exponent in the polynomial
In the given problem the largest exponent is 
so
Is a quadratic equation
therefore
The polynomial is a quadratic binomial
 
        
                    
             
        
        
        
Area of the sector = 1/2 * r^2 * theta where theta is the angle subtended by the arc at the center  ( in radians)
In this case m < theta = 360 - 235 = 125 degrees or  2.182 radians
So, the area of shaded area = 1/2 * 20^2 * 2.182 =   436.4 in^2
