The figure below is a regular polygon. What is the value of x? A. 10 B. 36 C. 144 D. 37
i know its not c
do you know the equation for the interior angles of a regular polygon?
i think
something like this?
yes! except that gives the total sum of all the interior angles so to find the angle of each interior angle if n = number of sides for a regular "n-gon" each individual interior angle = \(\huge \frac{180*(n-2)}{n}\)
so 180 and what not over 10?
yup \(\huge \frac{180(10-2)}{10} \)
ok
oh whale thats over 90
144
right?
yes, 144
;-; it was 10
The polygon shown is a decagon with ten sides and ten angles. The sum of the exterior angles of a polygon equals 360°. Since it is a regular decagon, all the angles are congruent. Find the measure of one exterior angle by the expression given below, in which n is the number of sides in the polygon.
I wasn't done
welp XD
I WASNT DONE
my bad
180 = 140 + (4x - 4) solve for x
tsk
good thing i got 9 more question
