25 has 3 factors: 1, 5 and 25. Only those 3 numbers can be evenly divided into 25. 1 is a factor for every number, 5 can be divided into 25, 5 times and a number is always a factor of itself as well.
Answer:
yes
Step-by-step explanation:
I am pretty sure. sorry if I'm wrong
Alright, so what we can take as a given is that arcDE/2= ∠CDE=2x+20 since the arc corresponding to the angle is 2*the angle. To solve for arcDE, we multiply both sides by 2 to get 2(2x+20)=4x+40=arcDE. Since the arcs in a circle add up to 360 degrees and we only have -20+30x and arcDE, we have -20+40+4x+30x=360 using the associative property. Simplifying, we get 20+34x=340. Subtracting 20 from both sides, we get 340=34x. Next, we can divide both sides by 34 to get 10=x.
Answer:
Step-by-step explanation:
<u>Use the formula:</u>
- degrees/360° = L/circumference
- or
- radians/π = L/circumference
<u>As per given:</u>
l = 12 feet, r = 10 feet
- degrees = 360°*12/(2*3.14*10) = 68.78°
- radians = π rad *12/(2π*10) = 0.6 rad
