m=y-y1/x-x1
m=4-4/-2-3=0/-5
m=0
Answer:
144
Step-by-step explanation:
54+90=144
144-90=54
90+54=144
144-54=90
Radius of curvature = 10'
Diameter of circle = 2 * 10' = 20'
height of segment = 2'
Let semi-chord be x.
Then by the intersecting chord property,
2*(20-2)=x^2
x^2=36
x=sqrt(36)=6
=>
chord=2x=2*6=12'
