Answer:

45 sides

Step-by-step explanation:

If each of the interior angles is 172 degrees, then each of the exterior angles is 8 degrees. Since the sum of the exterior angles of any polygon is 360 degrees, there are 360 / 8 = 45 exterior angles and 45 sides.

Which of the following equations models the relationship of angle A to the length of the line segment BC in the figure below.

Anastasy [175]

Let the line segment BD be x, then sin A = x/15
or, x = 15sinA
Also $y^{2} = x^{2} + (25)^{2} \\ = (15sinA)^{2} + 625 \\ =225 sin^{2} A+625 \\ y= \sqrt{225 sin^{2} A+625} 
$
The last option
