HELP PLEASE Find the value of each variable in the circle to the right. The dot represents the center of the circle

a = 43°

b = 90°

c = 43°

Step-by-step explanation:

Since, angle inscribed by a semicircle measure 90°.

Therefore, measure of angle 'b' = 90°

Since, measure of the intercepted arc in a semicircle = 180°

Therefore, c° + 137° = 180°

c = 180 - 137

c = 43°

Since, measure of the intercepted arc is double of the inscribed angle.

Therefore, 2(a) = 130°

a = 65°

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
