∠A is called inscribed angle. Inscribed angle is made from a point that attaches to the circle's circumference.
∠BOC is central angle. ∠BOC and ∠A are facing to the same side and because they are facing to the same side, they apply the rule of
inscribed angle = 1/2 × central angle
So we can find ∠A with this property
∠A = 1/2 × 132°
∠A = 66°
Circumference=2 times pi times radius
radius=0.5
circumference= 2 times pi times 0.5=1 times pi=pi inches
the circumference is pi inches or aprox 3.14 inches
The answer is y= x+3 because there’s no slope but there is a y-intercept
Answer:
34
Step-by-step explanation:
i think
STEP 1:
find the sales tax (decimal form)
x= sales tax
Cost + (Cost * Sales Tax)= Total
plug in known numbers
$9.40 + ($9.40 * x)= $9.87
9.40 + 9.40x= 9.87
subtract 9.40 from both sides
9.40x= 0.47
divide both sides by 9.40
x= 0.47/9.40
x= 0.05 sales tax decimal form
STEP 2:
find sales tax percentage
= 0.05 * 100
or move decimal to the right two decimal places
= 5% sales tax percent form
ANSWER: The sales tax is 5% (or 0.05 in decimal form)
Hope this helps! :)
