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
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
Subtract 36 from both sides
Divide both sides by 36
x=9

The intercepts can be found by setting the other variable to zero and dividing by the coefficient of the variable of interest. This tells you the x-intercept is -2/3, and the y-intercept is -2/1 = -2. The y-intercept is conveniently on a grid point. To find other grid points on the line, it is convenient to choose integer values for x, then solve for y.
y = -3x -2
Positive values for y will require negative values of x.
