I would say D, determine if it can be factored by grouping (sorry, I forgot to put in the answer here).
Answer:
180 degrees
Step-by-step explanation:
180 degrees would flip the triangle halfway through a full circle. B is A upside down rotated halfway through a full circle.
The answer is 2^(9/10). I did it assuming with the ^5 you mean the 5th root of 4
Answer:
18.50 times 3 equals 55.5, the answer is 55.50
Answer:
Area of Shaded Region 
Area of Semicircle 

Step-by-step explanation:
Area of Shaded Region = Area of Sector - Area of Semicircle
<u>Area of Sector</u>
Radius of the sector =20cm

<u>Area of Semicircle</u>
Since AB is the diameter of the semicircle
Radius of the Semicircle=20/2=10cm
Area of semicircle

Therefore, area of Shaded Region

Area of Square =20 X 20
