@Daniee_Bruhh do you know this
Yeah I think it's D. but I am not to sure. I know that if something is convex then it doesn't have points that go inward unlike concave that cave.
can you help me with more
yeah sure lol
ok can i post here
@Daniee_Bruhh
Yeah you can if you want lol
ok
The sum of the measures of the interior angles of a convex polygon is 3060º. How many sides does the polygon have? A. 18 B. 17 C. 19 D. 15
@Daniee_Bruhh
Hmmm.. I think the answer is C.19 It seems like the only one that is right.
What is the measure of each interior angle in a regular 15-gon? A. 120° B. 167° C. 108° D. 156°
D is the answer
The sum of the measures of the interior angles of a polygon is 720°. How many sides does the polygon have?
It has 6 sides. (x-2)*180=720. Therefore making x=6.
What is the measure of each interior angle in a regular 20-gon?
The answer is 162 degrees 180 x (20-2)/20 <-- the formula interior angle is 162 degrees
