Answer:
C
Step-by-step explanation:
C is congruent to A
289 square root = 17
17*17=289
Say 17 was length and 17 was width. L*w=289
Also, all sides of the square are the same.
I think it's B. not sure though u should wait. till someone else answer to see if I am right
Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).
A.

Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.

Indeed, those two numbers are relatively prime.
Answer:
C
Step-by-step explanation:
because vertical angles angles that are opposite each other and formed by two intersecting lines are congruent
hope this helps :D
