The length of the side = <span>The length of the arc intercepted by the central
<span>angle

</span></span>∴ length = Θ r
where Θ = <span>central<span> angle in radians
and     r  = radius

∴  </span></span><span>Θ = 70° = 70 * π /180
     </span><span>r  = 13 in.

∴ </span>length = <span>(70 * π /180) * 13 ≈ 15.88 in.

Martinez purchased a pair of shoes on a web site. the original price of the shoes was $75. she used a coupon code to recive 20%
tankabanditka [31]

Answer:

$9 or 9% less

Step-by-step explanation:

Original Price = OP

$75= OP

75 x .2 (20% discount) = 15

$15 discount

$75 - $15 = $60

$60 x .1 (service fee) = 6

$60 + $6= $66

Op ($75) - $66 = 9

$9 less than OP

How I check the percentage (probaly not how ur supposed to but ah well)

75 = 100%

75 + 25 = 100 but 25 more than 100%

66 + 25 = 91, also makes 75 100% again

100%-91%=9%

The diagram shows a right angle.<br> Write an equation to determine the value of x. Solve for x.
kramer

Answer:

8x + (6x + 6) = 90°

x = 6°

Step-by-step explanation:

because it is a right angle, the sum of the angles = 90°

8x + (6x + 6°) = 90°

simplify:

14x + 6° = 90°

subtract 6° from each side:

14x = 84°

divide both sides by 14:

x = 6°
