Answer:
20
Step-by-step explanation:
The distance between two points is found by
d = sqrt( ( x2-x1)^2+(y2-y1)^2
= sqrt( ( 10- -6)^2 + (-4 -8)^2 )
= sqrt( (16^2 + (-12 )^2)
= sqrt(256+144)
= sqrt(400)
= 20
make a rectangle, then take the side length and plug them into the Pythagorean theorem (a² + b² = c²)
16²+12²=c²
256+144=c²
400=c²
√400=√c2
20=c
