Answer:
9 and 12
Step-by-step explanation:
Pythagorean Theorem. One of the most common Pythagorean triples is 3, 4, 5 with 3 and 4 the legs and 5 the hypoenuse. That will make 9, 12, 15 anotther trible because you are tripling the side lengths. 12-9=3 so this triangle works.
The answer is 9y^2x(the 2 goes on top were the arrow is ) Hope this was helpful!
To solve for

To do so, you need to make both denominators 10 by multiplying the top and bottom of

by 5

=

Reduce by dividing both the top and bottom by 2
