Answer:
60 degrees
Step-by-step explanation:
The wheel is a circunference, so it has a total of 360 degrees. As we have 12 chairs evenly spaced, this 360 degrees will also be divided evenly, so the angle between each pair of chairs is equal to 360 / 12 = 30 degrees.
As we want the angle between chairs B and D, we have two spaces between chairs (the space between B and C and the space between C and D), so the angle is 2 * 30 = 60 degrees
Tan(32deg) = AC / 13.76
AC = 8.5982...
Y = -2x + 5
All you have to do when coming across this type of problem is substitute x and y for the points given, as well as change whatever b is, in this case 5, for b. For example: -3 = -2(4) + b

Answer:
Step-by-step explanation:
P(-2,-1) and Q(4,3)
average of x-coordinates = (-2+4)/2 = 1
average of y-coordinates = (-1+3)/2 = 1
midpoint of PQ: (1,1)
distance between midpoint and Q = √((4-1)²+(3-1)²) = √13
(x-1)² + (y-1)² = 13
