Number of angles = number of sides
180 - 120 = 60 (calculating the exterior angle)
360 / 60 = 6
There are 6 sides.
Hope this helps! :)

we know that
For a spherical planet of radius r, the volume V and the surface area SA is equal to
The
ratio of these two quantities may be written as
we know
therefore
the answer is
A= (a+b/2) × h
Is the formula for a trapezoid
