12/28 is equal to 3/7 (divide both the numerator and the denominator by the highest common factor).
I think it’s supplementary angle
Answer: The sum of all of the interior angles can be found using the formula S = (n - 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.
explanation: The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.
Answer:
B
Step-by-step explanation:
seeing input/ output boxes= function
y is proportional to some constant (k)(constant of proportionality) times x
y=kx
y=0.9(x)
plug and chug...
4(.9)=3.6
6(.9)= 5.4
12(.9)= 10.8
