<h3>Answer: x = 35 (choice D)</h3>

====================================================

Work Shown:

secant angle = (far arc - near arc)/2

angle BGC = (arc BC - arc AD)/2

40 = (115 - x)/2

2*40 = 115-x

80 = 115-x

115-x = 80

-x = 80-115

-x = -35

x = 35

For more information, you can search out "secant angles" and it should go over how the formula is set up and why it works.

If each interior angle of a regular polygon measures 180° how many sides does it have

Ne4ueva [31]

Answer:

This is impossible.

Step-by-step explanation:

The interior angle of a regular polygon is equal to

$\frac{180(n - 2)}{n}$

where n is the number of sides.

Setting this equal to 180°,

$\frac{180(n - 2)}{n} = 180 \\ \\ \frac{n - 2}{n} = 1 \\ \\ n = n - 2 \\ \\ 0 = - 2$

which is false.
