The distance from a point to a line is
distance(ax+by+c=0,(x0,y0)) = abs(ax0+by0+c)/sqrt(a^2+b^2)
So first convert the formula for the line to standard form
5x+2y=4
5x+2y-4=0
a=5, b=2, c=-4, x0=15, y0=-21
abs(5*15+2*(-21)-4)/sqrt(5*5+2*2)
= abs(75-42-4)/sqrt(25+4)
= 29/sqrt(29)
= sqrt(29)
= 5.385165 (approximately)

Step-by-step explanation:
Hey There so the first step of this problem is to find the formula for circumference
given some of the values we can form an equation to solve for the radius (r)
so we can conclude that the radius is equal to 5
30 22
20 18
(im sorry in advance if you get it wrong, but im sure you'll get it right)
Use the formula 1/2(base1+base2)height. Substitute the values.
