b= 126°

Step-by-step explanation:

OC= OB (radius of circle)

∠OCB= ∠OBC (base ∠s isos. △)

a= 27°

b= 180° -27° -27° (∠ sum of △OBC)

b= 126°

b= 2c (∠ at centre= 2 ∠ at circumference)

c= b/2 (divide by 2 on both sides)

c= 126° ÷2

c= 63°

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
