170° because: (130+105+90+45) = 370° regular: nAngle = Each Angle (for regular ones) = [(n-2)/n] * 180° 5Angle = [(5-2)/5]*180° = (3/5)*180 = 540/5 = 120° not regular: Sum(Complete) - Rest Sum= 540° Rest = 370° 540-370= 170°
Interior? Exterior? Interior= 180 x (n-2) when 'n' is the number of sides so for a 5 sided shape it is 180 x 3 = 540 degrees. 540=all the angles together 540 divided by the number of sides/angles is 108 Exterior= 360 divided the number of sides/angles (360 divided by 5) = 72 The total agle is 360 degrees but ech exterior agle is 72 degrees

The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 540 degrees
No, gram equivalent weight is molecular weight divided by n, where n is the number of equivalents of the substance involved in the reaction. It is not always equal to molecular weight divided by 2.
We use the formula that the sum is 180(n-2) where n is the number of sides. So 540=180(n-2)540/180-n-23=n-2so n=5 and it is a pentagon.(5 sides)
Where n is the number of sides of a regular polygon, the sum of the internal angles is equal to (n - 2) x 180. In the case of a pentagon, this is equal to (5 - 2) x 180 = 3 x 180 = 540 degrees.Therefore, the number of sides the polygon would have is 5.
