Answer:
218
Step-by-step explanation:
first find the area of the circle-

to find the area of the triangle, we need the base and the height. The base we know is 16, since we don't know the height yet, use the Pythagorean theorem to find the height. One leg is 16 the hypotenuse is 20 (2* the radius).

Now I know the height is 12. Find the area of the triangle
 
subtract the area of the triangle from the area of the circle
314-96=218
 
        
             
        
        
        
Answer: I believe those would be opposite angles (aka vertically opposite angles).
 
        
             
        
        
        
Answer:
A. 18 sit-ups in one minute
B. 30 doors per hour
D. 18 words per minute
F. $30 per night
C. 3.5 miles per hour
E. $10.50 per pair of pants
Step-by-step explanation:
A. 36/2 = 18
B. 15 * 2 = 30
D. 72/4 = 18
F. 150/5 = 30
C. 10.5/3 = 3.5
E. 31.50/3 = 10.50
 
        
                    
             
        
        
        
Answer:
135°
Step-by-step Explanation:
==>Given:
An inscribed quadrilateral ABCD with,
m<A = (3x +6)°
m<C = (x + 2)°
==>Required:
measure of angle A
==>Solution:
First, let's find the value of x. 
Recall that the opposite angles in any inscribed quadrilateral in a circle are supplementary.
Therefore, this means m<A + m<C = 180°
Thus, (3x+6) + (x+2} = 180
3x + 6 + x + 2 = 180
Collect like terms:
3x + x + 6 + 2 = 180
4x + 8 = 180
Subtract 8 from both sides:
4x + 8 - 8 = 180 - 8
4x = 172
Divide both sides by 4:
4x/4 = 172/4
x = 43
We can now find m<A = (3x + 6)°
m<A = 3(43) + 6
= 129 + 6
measure of angle A = 135°
