Answer:
the top one: 15.1
second box:11.8
Last box: 3.6
Step-by-step explanation:
The exterior angles of a regular pentagon has a measure of 360-108= 252 degrees
the sum of these exterior angles will be 5*252=1260 degrees
a regular nonagon (9-gon) has the exterior angles measure of 360 -140 = 220 degrees
the sum of these exterior angles of a nonagon will be equal 9*220=1980 degrees
so from these result that
the sum of the measures of the exterior angles of a regular 5-gon is less than the sum of the measures of the exterior angles of a 9-on

Answer:
504 millimeters (or 50.4 cm)
Step-by-step explanation:
Width of key in student calculator = 14 millimeter (1.4 cm)
Width of key in demonstration calculator = 2.8 cm
Thus, the demonstration calculator's dimensions are twice that of students' (in cm)
Also given, student calculator height as 252 millimeters (25.2 cm)
Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)
