Answer:
D. The player skates 12 m forward and then skates 12 m in the opposite direction.
Step-by-step explanation:
The player skates 12 m forward then back 12 m which means he is back to his starting point. :)
27 because the square root of 81 is 9 and 9 times 3 is 27.
The answer is B I think not 100%
A must be parallel to b.
Proof:
∠3 = <span>∠13 (given)
</span>∠15 = <span>∠13 (vertically opposite angles are equal)
Since </span>∠13 = ∠3 and ∠13 = ∠15, ∠15 = <span>∠3
Then, a must be parallel to b (transverse line d cuts parallel lines producing converse alternate angles that are equal (ie </span>∠15 = <span>∠3))
