Anyone knows this need some help pls ?!
1 answer:
Answer:
The art is rectangular because (0.5)²+(1
2)²=(1.3)²
Step-by-step explanation:
This is testing your ability to recognize a rectangle is fundamentally composed of 2 right triangles, and asking you to apply the Pythagorean Theorem.
Therefore, we shall do just that:
So, the art is rectangular, and the answer is the first one.

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.

There is actually a cool trick to this. When you see a and 2a, in this case 6 and 12, then the small triangle is a 60-30-90 triangle. The remaining side is 
.
This value rounds down to 10, and yep, you guessed it, another 30-60-90.
This time, x =
.
This is a very difficult problem and requires knowledge of the special triangles. Hope this helps!
