Answer:
s = 15.
Step-by-step explanation:
The formula for a polygon with s sides is:
Sum of the angles = 180(s - 2) so we have:
180(s - 2) = 2340
180s - 360 = 2340
180s = 2700
s = 15
3 : 3,6,9,12,15,18,21,24,27,30
4 : 4,8,12,16,20,24,28,32,36
7: 7,14,21,28,35,42,49,56,63
9: 9,18,27,36,45,54,63,72,81
Answer:
Small number = 19
Larger no. = 3(19)+14 = 71
Step-by-step explanation:
x + 3x + 14 = 90
4x + 14 = 90
4x = 90 - 14
x = 76 / 4 = 19
