Step-by-step explanation:
1.) The mean of 84, 92, 83, and 78 is 337
2.) 337 divided by 4 is 84.25%
3.) If you add 88 to 337 and divide by 5, you get 85%

Answer:
16
Step-by-step explanation:
(2 means squared) (c is the hypotenuse)
a2+b2=c2
a2+ (12×12) = (20×20)
a2+144=400
a2=256
a=16

Answer:
It's polyhedron, not polygon
Because above figure has merely 10 sides.
so the polyhedron above has 10 sides, each of them has 20°.
so total degree in polyhedron is > 180(n-2)
>180(10-2)
> 180×8
> 1440
