Answer:
10. 123º
13. 65º
Step-by-step explanation:
For number 10, a straight line is equal to 180º so all we have to do is subtract 57 (the number that we're given) from 180
For number 13, vertical angles are always congruent (the same) so we know that it's 65º
False. Negative numbers aren’t greater than positive numbers. For it to be true it would have to be -8<6.

Answer:
Solid Sphere
Step-by-step explanation:
According to the question, the three shapes have equal masses (m), radii (R) (and diameter).
The shape with the least mass moment of inertia will have the highest acceleration
Let IC represents Inertia
According to calculations, the inertia of
Solid Sphere: IC=(2/5)mR²
Solid Cylinder: IC=½mR²
Hollow Pipe: IC=⅔mR²
Where m = mass of the shape
And R is the Radius of the shape
By comparison, the solid sphere has the least mass of inertia and hollow Pipe has the most mass of inertia.
So, solid sphere will get to the bottom first.
