Answer:

1. (19x - 49)+(5x + 37) = 180

2. 77°

Step-by-step explanation:

1. Since the two arc measures will equal 180°, you can write the equation (19x - 49)+(5x + 37) = 180

2. By solving the equation, we can find that x=8. Plugging in the value for arc CD's equation, you will find that it is equal to 77°.

Answer:

$x = - 0.4$

Step-by-step explanation:

$\frac{2}{3} (x - 2) = 4x$

Expand with the distributive rule:

$\frac{2}{3} x - \frac{2}{3} \times 2 = 4x$

$\frac{2}{3} x - \frac{4}{3} = 4x$

Add 4/3 to both sides:

$\frac{2}{3} x = 4x + \frac{4}{3}$

Subtract 4x from both sides

$- \frac{10}{3} x = \frac{4}{3}$

$- 10x = 4$

$x = - 0.4$
