Answer:

the value of x is 9

Explanation:

Tangent chord angle = half of intercepted arc

4x+19 = half of minor arc DE


4x+19 = (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
