Answer:
Reflex angle
Step-by-step explanation:
Properties of reflex angles:
1). Any angle measuring between 180° and 360°.
2). Other side of the reflex angle is either acute or obtuse angle.
By these properties,
Since, angle C measures more than 180° but less than 360° and opposite angle is an acute angle.
By these properties angle C and angle D are the reflex angles.
Answer:
Step-by-step explanation:
9m-3(m+6)=2(m+1)
9m - 3m - 18 = 2m + 2
6m- 18 = 2m +2
4m = 16
m= 4
Answer:

Step-by-step explanation:
since C = πd, the diameter is 25.
So, the radius is 12.5
.........................It is 40.
Answer:
There is a circle with a diameter[d] of 2.
Step-by-step explanation:
the Radius=diameter /2=2/2=1 units
now
circumference=2πr=2×π×1=6.29=6 units
area=πr²=3.14 unit²
