formula for interior angles of a polygon is 180 times the number of sides minus 2
20 a 20gon has 20 sides, 20 -2 = 18, 180*18 = 3240
sum of interior angles = 3240 degrees

The question is an illustration of selection (or combination)
The number of lock combination is 343
The given parameters are:
<em />
<em> --- the number of digits to select from</em>
<em />
<em> --- the number of digits the lock uses</em>
<em />
Because the digits can be repeated, the number of lock combinations is:
So, we have:
Hence, the number of lock combination is 343

The slope of the line that passes through (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(p,a) and (p,-a)
slope=(-a-a)/(p-p)=-2a/0=undefined
means
the slope is undefined
x=something
(x,y)
(p,a)
x=p is the equation
the equation of a perpendicular line is y=k where k is any real number
the y intercept of y=k would be y=k or the pont (0,k)
