Answer:
(b) 36 degrees.
Step-by-step explanation:
K is the center of the circle so triangle KMN is isosceles and m < KMN = m KNM = 26 degrees ( base angles are equal)
So m < LMK = m <LMN - m < KMN
= 98 - 26
= 72 degrees.
Now triangle LKM is also isosceles since K is the center of the circle so
m < LKM = 180 - 2* 72
= 180 - 144
= 36 degrees.
Answer:
there are 48 possible seating arrangements.
Step-by-step explanation:
This can be calculated using the rule of multiplication, in which the number of options depends on the following cases:
- Betty is sitting on the 1st middle seat:
<u> 3 </u> * <u> 1 </u> * <u> 2 </u> * <u> 2 </u>* <u> 1 </u> = 12
Aisle Seat 1st Middle Seat 2nd Middle 3rd Middle 3rd Row Seat
In this case:
- There are 3 options for aisle seat: Archie, Jerry or Moose.
- There is 2 option for 1st middle Seat: Betty.
- There are just 2 options for the 2nd Middle seat because Veronica can be beside Betty.
- There are 2 options for 3rd seat: The two friends that we doesn't assign a seat yet.
- There is 1 option for 3rd row seat.
At the same way, we can calculate the possible seating arrangements in the following cases:
- Betty is sitting on the 2nd middle seat:
<u> 3 </u> * <u> 2 </u> * <u> 1 </u> * <u> 1 </u>* <u> 1 </u> = 6 Aisle Seat 1st Middle Seat 2nd Middle 3rd Middle 3rd Row Seat
- Betty is sitting on the 3rd middle seat:
<u> 3 </u> * <u> 2 </u> * <u> 2 </u> * <u> 1 </u>* <u> 1 </u> = 12
Aisle Seat 1st Middle Seat 2nd Middle 3rd Middle 3rd Row Seat
- Betty is sitting on the adjoining seat in the third row:
<u> 1 </u>* <u> 3 </u> * <u> 3 </u> * <u> 2 </u> * <u> 1 </u>= 18
3rd Row Seat Aisle Seat 1st Middle Seat 2nd Middle 3rd Middle
So, there are 48 possible seating arrangements and it is calculate as:
12 + 6 + 12 + 18 = 48
