Answer:

the value of x is 9

Step-by-step explanation:

Tangent chord angle = half of intercepted arc

4x+19 = half of minor arc DE

$4x+19 = \frac{1}{2} \ of \ minor \ arc \ DE$

Multiply by 2 on both sides

minor arc DE= 2(4x+19)= 8x + 38

sum of angle in a circle is 360 degree

minor arc DE + major arc DE = 360

$8x + 38 + 28x-2= 360$

$36x + 36= 360$

Subtract 36 from both sides

$36x=324$

Divide both sides by 36

x=9

Tennis racket marked up 50% to $36.76

Kaylis [27]

I asssume we want to find the original price
so marked up 50% means if original price=100, then marked up price=50+100=150%

so
36.76=150%
hack, since 150=3 times 50 and 2 times 50=100, divide 36.76 by 3 then mutiply by 2

36.76=150%
divide both sides by 3
12.25333333333=50%
multiply both sides by 2
24.5=100%
original price=$24.50
