Each angle in a regular polygon measure 171 degrees. how many side this polygon have?

40

Step-by-step explanation:

For any polygon

interior angle + exterior angle = 180°, that is

171° + exterior angle = 180° ( subtract 171° from both sides )

exterior angle = 9°

The sum of the exterior angles of a polygon = 360° , thus

number of sides = 360 ÷ 9 = 40

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
