What is the angle of rotation of this regular decagon? What is the measure of an interior angle?
SCORPION-xisa [38]
A decagon has 10 sides. If the polygon is symmetrical, the angle of rotation is given by the following equation:

360 / (number of sides)

Therefore, 

360 = 10 = 36.

The interior angles are determined by the following equation:

180 - (angle of rotation)

Therefore, 

180 - 36 = 144

The answer is A.

The product of two consecutive integers is 420 which quadratic equation can be used to find x the lesser number
Fynjy0 [20]

Answer:

Step-by-step explanation:

If the smallest number is 'x', then the other number = x +1

x*(x+1)= 420

Use distributive property

x*x + x*1 = 420

x² + x - 420 =0   ------> this is the required quadratic equation.
