Step-by-step explanation:
The formula for arc length [for the angle in degrees] is:

here,
= degrees
= radius
using this we'll solve all the parts:
r = 10, n = 20:


from here, it is just simplification:
2 and 360 can be resolved: 360 divided by 2 = 180

10 and 180 can be resolved: 180 divided by 10 = 18

finally, both 20 and 18 are multiples of 2 and can be resolved:

Option (E)
r=3, n=6:


Option (D)
r=4 n=7


Option (C)
r=2 n=x


Option (D)
r=y n=x


Option (E)

Answer:
143
Step-by-step explanation:
90-53=37
180-37=143
For <u> the following subtraction problems 17t 13lb 3oz - 9t 20lb 9oz the output is oz = 7 T 1992 lb 12 oz</u>
Step-by-step explanation:
Let us first consider that
<u>1 T = 2,000 lb</u>
<u>1 lb = 16 oz</u>
Here we will convert all the measure units to oz, subtracted the amounts, and finally converted the units back to their original ones.
<u>17t 13lb 3oz - 9t 20lb 9oz (The equation given to us)</u>
<u>It can be rewritten as </u>
=17 T or (2,000 lb*17) + 13 lb + 3 oz) - (9 T or (2,000 lb*9) + 20 lb + 9 oz)
= (34,013 lb or (16 oz *34,013) + 3 oz) - (18,020 lb or (16 oz *18,020) + 9 oz)
= 544,213 oz - 288,329 oz = 255,884
<u>oz = 7 T 1992 lb 12 oz</u>
