Each exterior is 360/7 = 51.4 degrees to the nearest tenth
Each interior angle is approximately 128.57 * * * * * That is only true of a REGULAR heptagon. The question does not state that it is regular.
51.428571° is the measure of an exterior angle of a heptagon. You can always find the measurements of a regular polygon by dividing 360 by the amount of sides.
360/7 = 51o25'42.86''

360/7 = 51.43 degrees (approx).
It is the regular triangle whose exterior angles are greater than the regular heptagon

900/7 = 128.6 degrees rounded to the nearest tenth
An exterior angle is 360/7 = 51.4286 degrees. So interior angle is 180 - exterior angle = 128.57 degrees (approx).
Each exterior angle will measure 360/18 = 20.0 degrees
That depends on the type of triangle it is but if it's an equilateral triangle then its exterior angle is greater than that of a regular heptagon
