Answer:
The area of sector AOB is 75.36 unit²
Step-by-step explanation:
Consider the provided information.
Circle O with minor arc AB=60 degrees and OA =12.
We need to find the area of sector.
Area of the sector: 
Substitute
and r =12 in above formula.




Hence, the area of sector AOB is 75.36 unit²
Answer:
EF=22
C=70°
B=110°
Step-by-step explanation:
Trapezoids have to have a total of 360° and there are complementary angles.
Answer:
Five x squared plus two
Step-by-step explanation:
An exponent of two is always pronounced as "squared"
we have
----> inequality 1
The solution of the inequality 1 is the shaded area below the solid red line
The solution is the region D and region C
-----> inequality 2
The solution of the inequality 2 is the shaded area above the solid blue line
The solution is the region B and region C
The solution of the system is the common area
so
The solution is the region C
see the attached figure
therefore
the answer is the option C
Region C
