Question

What will be the sum, in degrees, of the measures of the interior angles of this polygon when it is completed?

A.720°

B. 1080°

C.1440°

D.900°

Answer 1

sum of exterior angles of a polygon with any number of sides = 360
U can find the exterior angle using the given data.
180-144=exterior angle
exterior angle = 36
To find the number of sides divide 360 by the value of an exterior angle.
360/36=10
Nw sum of interior angles=(n-2)*180
where n is number of sides.
sum = (10-2)*180
=8*180
=1440
